I'm just curious....orange drop content
« on: October 14, 2022, 12:49:57 am »
I tried some in the tone stack and on a coupling cap to the 3rd stage of the pre a of a marshall style preamp on a 6V6 output build in place of mallory and i really liked the result. They just seem to have better clarity and the bass notes were clearer and tighter which was what i wanted. Not a huge difference at first, but the more i played it the more i began to notice and overall more focused tone. I always read they were good in fenders but not so much in marshall style amp. Mine has a 3 stage pre with marshall style details and a cathode follower into a typical marshall tone stack. I really consider this a nice improvement and i posted just out of curiosity....what do some of you feel about them compared to mallory and sozo etc? I'm considering replacing the rest of the signal caps in the amp with them now.

I tried some ...

FYI the 'orange drop' description covers several product lines using differing technologies. Hence you need to identify which particular product line is being referred to.

Yeah, i know but i'm not so sure it's the "orange drop" that makes the difference as much as the different type of cap. In any case i only know one of them is a mallory and the other 2 not sure. One looks like a sprague but doesn't have a "715" or the name on it so not sure. That brings up another question...is there a general consensus whether spragues are superior or mallory or what? I realize it's subjective but i want to buy some and if most say brand A is best i'd buy that over brand B given no other way to know.

CDE Orange Drop 715p and 716p series are polypropylene film/foil caps. The 716p series is a compressed design, thinner than the 715p series. Both series are rated at a maximum of 600 VDC. The 418p, PS, and 225p series caps are polyester film/foil caps. The 225p caps are a compressed design, thinner than the 418p caps. The 418p and PS  caps are rated at 600 VDC. The 225p series are rated at a maximum of 400 VDC. I'm not sure, but, I believe that all of the caps are constructed with aluminum foil. Howard Dumble was reported to have preferred the 418p series. The PS series is supposedly the same as the 418p series.

Who makes the PS series today? It's all so confusing...sprague, mallory, CDE and 1 of 2 others seem to have all made orange drops and PS series seems to have been/being made by different companies and now i hear the 418 is the same as PS but who makes or HAS made the 418 ! Need to take a class on orange drops just to figure out what to buy and how to recognize the exact one ! I keep reading of people saying the PS is their fav and now i hear the 418 would be the same. If i want PS what do i look for? Brand? Codes? NOS? New? I'd bet theres not much difference as long as they are the same construction but if i'm gonna pay as much as they cost i want to make sure i get PS/418 and the right era/manufacturer.

Thats what i have always used but this experience has changed my mind. Theres a clarity and solidness to the tone compared to the 150s and to see if i was just placebo-ing out i put the 150s back but when it did it became even more apparent. Like i said, it;s not huge but when it comes to great tone the difference between good and great or great and magical can be tiny. Sozo i find are opposite. Dark and murky, loss of clarity and percussive attack. Again not huge but in this case quite obvious.

I used to use a lot of the 700 series orange drops.  I found them exactly as you described...tended to give a tighter, clearer sort of sound/feel, at least in the circuits I used them in.  I never really warmed (pun intended) to that though, so I found I much preferred the Mallory style polyesters which gave me a warmer, or less tight/sterile feel.  All of that's subjective though...I do have one amp which extensively uses 700 series orange drops throughout, and it's really warm and lovely.  I also found I liked the orange drops as tone caps in guitars.

I guess I can see that depending on the amp but in mine thats not an issue at all. But I have a lot more tweakability than most any production amps because i like having a lot of control like a variable NFB pot for example among 4 or 5 other switchable things not typically found on a production or even boutique amp.  So i can dial in a smooth darker tone thats not remotely close to sterile but retains that little edge of clarity now with the orange drops.

Thanks. Are there any markings on them to denote that they are made by CDE? They show only a pic in the PDF spec thats not clear even when zoomed in. Also, if the ps and 418 are the same, why do they show both in their catalog?

If you purchase the capacitors from a reliable vendor such as Antique Electronic Supply you can be sure that they are CDE capacitors. If you purchase the capacitor from some goober on FleaBay, who knows what kind of counterfeit Chinese crap you may be buying.

Quote from Tubes and More regarding 418p and PS capacitors.

Question: "Are these real 6ps caps? Who makes them and what are the markings on them?"

Answer: "Yes these are real 6PS caps and are marked CDE6PS. Some will be marked as CDE418P but this is the same thing as the Type PS. In other words, the 418P series will have different options (tolerances, capacitance, lead styles,etc) and the Type PS simply has specific options from the 418P series that makes it a Type PS. Both types come from the same manufacture and we have confirmed that they are identical in spec."

This seems counter initiative to me but maybe someone can comment on why this happens. I have a .1uf 600v sprague that says 6ps-p10 on it. I know this cap is at least 30 years old. I have another that i assume is a sprague and i believe is equally as old that doesn't say "sprague" on it like the .1uf, but it probably is a sprague and it says 418 on it and this one is a small value, .0047uf and also 600v.  For the heck of it i tried both in place of the mallory 150 between the pre PI master and the PI. The big cap had a really apparent spiky uncompressed sounding top end that i would say is what most call sterile and the .0047uf sounds smooth and very nice. In fact, the .022 mallory that was there before doesn't seem to sound much fuller and certainly not as beautiful. If and when i buy some more .022 OD's i will try one of those there and see if it's just the value difference or the orange drop. But i'm curious why a much bigger cap would have that excessive top. Don't smaller values have as much top but less lows? So if anything i would have expected the opposite. And the .0047 sounded much more balanced and transparent.

If your circuit is a LTP PI you need a small cap. Marshall liked .02 and Fender liked .001.

Most marshalls seem to have .022, at least the ones i've owned of looked at. Never saw one with a .0047uf in that part of the circuit. Since most Fenders don't have cascaded gain stages i can see why they'd use a bigger cap. But i haven't seen a lot of amps using .0047uf there. Actually can't think of one offhand tho i'm sure there are. Think i'll pull one of the .02uf OD's in the tone stack and try it there. Might make more of a difference than in the tone stack.

EDIT: just realized you said a .001uf for fenders. That too seems counter intuitive to me tho maybe bigger caps earlier on are why.

The input impedance of the LTP PI is much larger than the resistor values. This is due to the bootstrap biasing. That's why you only need a small input cap. Heck, the AA864 Bassman used a 500pF!

I believe you, but why do they use much higher values than that like a .022uf? Is it that anything over the minimum "required"  has no effect so they just use whats the most common cap in the inventory? Just curious.

Thats mostly over my head but the values shown in the example are different. They say use as small a value for the input as u can get away with. My PI has 1M where that PI shows 470k, a 1.6k cathode where mine is 470R, and tail is 10k on mine vs 47k in the example. They are saying a .01uf minimum which is twice the size of the .0047uf i liked.  Would the differences in the values i listed mean i can get away with a smaller minimum than in the example?

The 10 nano-farad reference is for a turn over frequency of 20 hz. Low E on a guitar is about 80 hz. Look at the formula that was referenced.

"so 470k grid-leaks give an input impedance close to 940k.

Because the grids are at a high DC voltage, an input capacitor is required to block the DC reaching previous stages in the amp. The input coupling capacitor may be chosen in the same way as for any coupling capacitor:
C = 1 / (2 * pi * f * R)
Where:
f = the lowest -3dB to be passed.
R = the source impedance of the previous stage plus the input impedance of this stage. However, often the source impedance is small enough compared with the input impedance that it may be ignored.
For example, using 470k grid-leaks gives an input impedance of approximately 940k. Taking f = 20Hz:
C = 1 / (2 * pi * 20 * 940000)

So, using the same formula with a turnover frequency of 80 hz. C = ~.002
C = 1 / (2 * pi * 80 * 940000)

My math skills....well, they are literally non existent. And if it's not dead apparent, i'm not a tech. But the only thing i can sorta understand from all that is .0047uf would be considered too small. I did try one of the .022uf OD's i had in the tone stack but the .0047uf just seems so much more transparent to me. It just gives that kind of tone that is 100% un bloated and balanced to where it feels like everything in the amp is working in harmony. We'll see how i feel in time but for now it's staying in because it seems to sound very notably better then the .022uf. Or to put it another way, it just sounds and feels right. Seems that particular part of the circuit is critical as far as cap value if not brand/type.

Well this is a bit strange. Never liked sozos back when i was building amps (just started tweaking tube amps again after about 8 years) but i saved them and I had a thought that made me want to try them in this amp. I don't know if it's because this one is 6V6 and all the others were 50 watt EL34's, but for whatever reason i swapped out the OD's for sozos that have been in the parts box for years and i hear them very differently now. I don't know if it's my ears having changed or what  but i'm really liking what i hear. They sound richer than either the mallory or OD's and i think the dark murky sound i remember is balanced out by this amps brighter character. (and ability to get very bright with the switches and such i have in it) I'm going to replace all signal caps with them and see what happens. If it'd overkill i'll replace some with OD in parts of the circuit i feel they'd be best in. And thanks for the link, i'll definately read that when i get a chance.

I think now i know why some like and some dislike sozos and why i didn't before. As i said i put 2 in the tone stack and one between the master and PI and liked it. So i did all the rest in the preamp and the presence cap too. Overkill. Sounded fantastic for full on dirt but as i rolled my volume back to clean up it didn't clean up well. So tomorrow i'll have to replace the most suspect sozos one at a time to see which one or ones are causing that. I think the perfect balance will be combination of sozos and orange drops. This will take some ear burning so i have my work cut out for me.I also have a few vintage model sozos. Maybe i should try those tho i recall them sounding rather muddier. Then again....i thought the regular ones were muddy back then ! So maybe i'll give those a try. Only have 3 tho i think.

I have tried to like Sozo’s.
They cost more money, they must be better…right?
It seems that I like the 6PS OD better—just about always.


I also have found that Silver Mica pF caps are not pleasing me—including the huge Sozo brand.  I’ve replaced most all SM’s with ceramic discs and find it is much more pleasing to my ear.

I'm starting to feel the same. I spent the morning swapping caps and i really don't wanna keep going down this rabbit hole and i don't think i will have to because i'm coming to some solid conclusions. First is the sozos sound great for overdrive. I mean REALLY great. Fat and smooth and rich. Second, they sound lousy for cleans and not great for those slight edge of distortion sounds either. Lastly, as i have felt from the moment i tried them, the OD's sound great anywhere you put them. I have moved the few i have to the preamp gain stages and one between the master and PI as i had it before i tried the sozos. I guess the takeaway is the sozos impart a not great sounding distortion of their own, especially if not only when in places where there's big signal. I'm going to see how i feel with mallorys in place of the sozos that are still in the TS and eventually i think i'll b going with my initial plan to replace them all with 6PS OD's. They impart or allow what i call clean distortion which i really like.

The Mallory 150's work great, but I really appreciate the small Nichicon and Panasonic caps, which seem consistent to me.   I can't tell the difference between polyester and polypropylene as a base for the metallized film. 

Most of the Orange drops are just too big.

And, if I'm honest, I can't stand the look of those things . . .  though lots of people want them in their build. 

Truth is, I don't think there is a real "sonic" difference between similarly rated modern film capacitors, at least as far as my old (but well used!) ears.   I'm well aware there are many other opinions out there.

I hear a huge difference depending on the caps you are comparing and the amp, the way you use it, etc. Other times not so much. By the way, during this testing of caps i do notice the mallories also have that distortion of their own like sozos but it's far less obvious. I think it adds to the richness of the tone when overdriven but clean it's detrimental. I didn't really notice it till i tried the OD's and experienced overdrive that cleans up much better.

EDIT: I don't think i have to go out on a limb to suggest that if you did a poll you would probably find that the players who use classic rock type/degree of overdrive and get their cleans by rolling down the guitar volume are the guys that are orange drop people and those why play hard rock and never use very clean tones unless via a second clean channel are gonna be the sozo people. Just e and my ears talking, but thats what i hear. I'm going 100% orange drop.
By the way, I hear people say caps sound different when the break in usually with regards to sozos and mallory. Is this also true of orange drops?

Be careful. Snake oil does not wash off easily!    :l2:
A schematic, layout, and hi-rez pics are very useful for troubleshooting your amp. Don't wait to be asked. JUST DO IT!

I'll take that as a no, they don't change nor do any caps. I think i'm done anyways and won't need to buy any more caps. Turns out after a lot of musical chairs i like all orange drops BUT, one sozo as the very first coupling cap into the gain pot. It was quite obvious as soon as i did that. It gives me some of what i liked about then but still cleans up nice. I have to assume thats because it's in a place where the signal is not yet multiplies too much so the cap is not adding too much of it;s own distortion. Just a guess. In any case i'm done with caps. Just gotta clean up all the slop from playing musical chairs with solder and caps. I will say this, i certainly learned that there IS w/o a doubt a difference that may or may not be far less noticable depending on many factors like the amp, playing and setting style, ears, etc. But it's there and it can matter considerably. I've always felt the difference between a good tone and a really great tone can be only a very subtle difference that just takes it over that dividing line.

My comment was aimed directly at your "caps sound different when the break in" comment.

Now you need to compare resistor brands. That's where the real mojo is. Of course they need to be properly burned in.  :wink:

Yes, i realize that and responded by suggesting i'll take your word on it. I never experienced it myself, just read about it and therefore wondered if i will need to take that into account if i buy some more OD's. But like i said i don't because i got the thing sounding really good. And if anyone thinks i'm being "placebo'd",  consider this. Since i put the ODs back everywhere but where there was a mallory before, then put ONE single solitary sozo in that position, my amp now feeds back so much easier and quicker theres no mistaking it. Notes that before would not even sustain long are now breaking into harmonic feedback. It has NEVER done that before. One thing i have always found with cascaded circuits is when they sound their best they do that at the drop of a hat. It's strange, but ONE sozo as the first coupler before the gain pot made that difference and made the amp sound more harmonically rich. crazy. But it won't do that if i replace the rest of the OD's with sozos or mallories. It just seems that one spot is where that sozo sound matter and elsewhere it just ruins the cleaner sounds. By the way, i realize u r being sarcastic but i HAVE experimented with carbon comp resistors and t never noticed anything worth noting.

CDE Orange Drop 715p and 716p series are polypropylene film/foil caps. The 716p series is a compressed design, thinner than the 715p series. Both series are rated at a maximum of 600 VDC. The 418p, PS, and 225p series caps are polyester film/foil caps. The 225p caps are a compressed design, thinner than the 418p caps. The 418p and PS  caps are rated at 600 VDC. The 225p series are rated at a maximum of 400 VDC. I'm not sure, but, I believe that all of the caps are constructed with aluminum foil. Howard Dumble was reported to have preferred the 418p series. The PS series is supposedly the same as the 418p series.


Another difference between the 715p is the 716p is that the 716pare made with tin plated copper leads and the 715 are tinned copper-clad steel. Adiophools note that as an improved sonic characteristic. Bah! Also, the 715 are available in 1% tolerance, 716 have a best tolerance of 3%. Both series are available with ratings to 2KVDC.

by the way, in addition to acquiring the Orange Drop line from SBE, Cornell-Dublier also owns Mallory NACC and Illinois capacitor.
I suppose one way to avoid class action lawsuits for colluding with other manufacturers to fix capacitor prices is to be the only one making capacitors.

"Sprague" has been gone for decades. The old Sprague factory in North Adams, Massachusetts has been turned into an Art Museum.

I think ETR makes most of the orange/brown drop capacitors for other companies.  https://www.justradios.com/DMEcapacitors.html


And David at Just Radios carries the 1600v versions of the Orange Drop metallized polypropylene film caps that are more compact in size.  http://www.etr.com.tw/eng/dc_use_film_capacitors/m_polypropylene/dc02_02.htm

So, when CDE purchased the orange drop line, they bought all the tooling and machinery from SBE (Sprague-Barre). Last I checked (years ago), they continued production of Orange Drops at the SBE facility in VT, but their long term plan was to move the tooling and jobs to Mexico at some point.
I'm sure they've move production by now. SBE sold off the remaining assets and shut down. They essentially re-emerged as Advanced Power Conversion Solutions to manufacture critical components for the EV industry.
CDE's headquarters is actually not far from me in New Bedford.

Where is the Orange Drop product mentioned? I see no reference to Orange Drop. The product listed is for a generic metalized polypropylene film cap.

CDE lists manufacturing plants in the USA and Mexico. It looks like the main plant is located in South Carolina.

So an ETR cap to you is generic.     OK  whatever  maybe you could read what is manufactured in those plants in your link.

The point is, they do not manufacture Orange Drop caps. They manufacture a metalized polypropylene film cap. They do not produce a film/foil cap. ETR is a large Chinese company that makes a lot of capacitors. Quantity does not equal quality.

Furthermore, these ETA “Orange Dips” are clearly off topic, as this thread is intended to discuss Orange Drops.
