I want to make sure I get the right Mercury Mag. They don't show specs on site but I'm pretty sure its the FTTP/M,

The stamped white ink label is wore off. I should have kept some blue painters tape on it while I was working on it. (I'll look for the lead hook up sheet they sent with it.)

I think the # you posted is correct but I think at the time they didn't have the 'lower B+' model.

Just call them and ask to make sure. I always order on the phone from them to get it right.

That's a big pain with them about not listing specs, like it's a big secret that only Leo and they know.

Holy shit those 5U4GB's are expensive, well for the name brand Nos at least. They go from $19-$150 bucks. You have any preference

and 1 of the heater wires sparked to the K sleeve,

The heater wire is inside the cathode sleeve inside the tube. The heater heats the K and is very close to the K.

Was it only happening when you would put probe on and off or happening as you kept probe on?

It was as I held the probe on the tube pin. Put the spring clip hook on and it was fine.

I have no idea who I bought the tube from, it was 2, 3 years ago already. Got it from 1 of the legit tube guys, like Angela, someone like that.

I know better that I should always pop new tubes in an amp when I 1st get them.

You have another regular probe to try out besides the spring probe? When ever I have a flakey probe & I have to order a set I buy two. I got caught with a bad set once and the HVAC unit tested powered off. I got hit with 208/230 and well you know the rest.

lego4040 · « **Reply #105 on:** January 16, 2015, 09:50:04 pm »

I'm here in Manhattan, NYC. I buy my tubes here lately http://www.audiotubes.com. Mom and Pop shop kind off and always polite on the phone. They have stock up the ass and have always givin me alternatives to the high end stuff. They hooked me up with great 6v6's for my last build and they were cheap/NOS and in fantastic shape and readings.

Willabe · « **Reply #106 on:** January 16, 2015, 09:50:13 pm »

I have 3, 4 sets of probes but it's not a bad probe. Works fine for everything else I tested today, just that 5V4.

And the little spring hooks are great to use on some things, their so small it's very hard to short them to anything else.

Brad

lego4040 · « **Reply #107 on:** January 16, 2015, 09:53:24 pm »

Best not use tha 5v4 then, wouldn't want to ruin that amp

Willabe · « **Reply #108 on:** January 16, 2015, 09:55:11 pm »

Doug has new EH5U4GB's for $16, wouldn't hurt to have 1 to use until the amps up and running so if you kill no big loss.

Might be very good as far as B+v? The new 5Y3's give a higher B+ and are fine for amp builds if you want a little higher B+.

After it's tested for bugs then you can put in a NOS.

Brad

Willabe · « **Reply #109 on:** January 16, 2015, 10:20:19 pm »

At the link you just posted (and I live like ~15 miles from them

) they have 5U4GB's, US made, from $15 to $35. Any of the US made NOS will be fine. (As you read his info on them he tells you many are just relabeled RCA or GE both great US made tubes.)

The GB's are straight sided like a 6L6, the GA's are the bigger ST shape with shoulders, more like a Coke bottle shape and their taller and fatter. I like the smaller GB's. Look at the pictures of the 5U4GA and GB Doug sells.

http://hoffmanamps.com/MyStore/catalog/parts11.htm

And he's got a new Sovtek 5V4 for $13.50. (I think I bought 1 from him not long ago, now where did I put that?

)

Looks like you saved yourself shipping fees Brad. I like the descriptions and the choices, like a kid in the candy shop. I bought tubes from him, Doug and some other place where I get my JJ's. I broke two JJ's on my amp rig

I forgot I had them in when testing, I tilted the chassis down for readings and crack, thank god I power down and discharge caps every time before I do anything with a open amp. R.I.P. jj

Tracking for the stuff I ordered says its in mailbox? Super says he'll check in the morning in the big mail boxes, God do I hate the usps delivery system, hey Doug, I will gladly pay and wait longer if necessary to us UPS. So for the cabinet and chassis, my options are the 5E5A&5E7 chassis is my easiest option. As for a cabinet, it's either the 1x15 or I have a baffle made and go down to a 1x12 in the 5e5a cabinet thru weber. Anyone have a different option? I could go with the 3x? In the bandmaster cabinet, neighbors will love me

Willabe · « **Reply #116 on:** January 20, 2015, 08:19:54 pm »

The 5G9 came with a single 12" in but it was in the tweed Pro cabinet not the smaller tweed Deluxe (5E3).

When TQR mag. bought an old 1 and did a review of it they said they were nicely surprised with how much fuller it sounded in the Pro cab then the vintage 5E3 they have.

Willabe · « **Reply #118 on:** January 21, 2015, 10:47:34 am »

No, but from the amp companies they list as clients, if their still clients then their very good cabinets.

They look real nice, very good looking dove tails.

I seem to recall TQR mag talking about them more then a few times. Lead time at 13 weeks is a little long.

Willabe · « **Reply #120 on:** January 21, 2015, 12:24:42 pm »

Seems that they have more orders then they can handle, which speaks to their reputation, unless they expand the shops capacity, because of return orders? And he probable doesn't want to do that. The bigger your company gets the harder it is to control the quality and you end up doing more paper work in the office than out in the shop doing hands on building.

(They probable fill their big return costumer orders, ie, amp companies 1st?)

Have you already drilled your extra holes in the board?

lego4040 · « **Reply #128 on:** January 24, 2015, 11:55:10 am »

I didn't drill the holes for the pass thru wires yet. You have some advice, I already see I ordered wrong caps on the .02's. I ordered .002

lego4040 · « **Reply #129 on:** January 24, 2015, 03:06:45 pm »

Those lugs to the top left are where the mains go, then the go down to the lugs below it. I was thing about just sending mains to where they go and then not have to use under board wire. That frees up the top three and maybe use those for adding bias pot, I just need to figure a clean way to do it. I figured a clean way, I need the 18-25kish resistor from the wiper to the lug attached to caps. The yellow wire underneath is where leg one goes to cap. I'll have to order my stuff tonight.

sluckey · « **Reply #130 on:** January 24, 2015, 03:24:36 pm »

The diode is backwards and you are missing two resistors in the bias circuit.

lego4040 · « **Reply #131 on:** January 24, 2015, 03:48:47 pm »

:icon_biggrin:those are the two I have to order from Doug tonight. The 82k that goes between the cap negatives. And the 22k( that would be the one I penciled in) you didn't pick up on the 470ohm before the rectifier(that I have to flip around). You posted a drawing using 100k-220k which i am is assuming is If I use a PT without the -50bias tAp. I put a 470 because I am going to buy the Mercury mag that is for this amp which will allow me to use the 5U4. If I'm wrong with the 470 resistor let me know, I correct that as well

sluckey · « **Reply #132 on:** January 24, 2015, 04:02:05 pm »

I saw the 470Ω. I also knew you were still flopping around about which PT to use so there was no need to mention it .

lego4040 · « **Reply #133 on:** January 24, 2015, 04:45:35 pm »

I went to your site Steve and was looking at your tweed build for some pointers and really nice pictures. On your Tweed Deluxe build you put 1 watt resistors off of pins 1&6 on your preamps. I didn't have 1 watts, only 3watt. And I only put them on the second preamp at the moment. So I put the bigger 1watts on those preamps? Original schematic doesn't show the to be 1 watters

sluckey · « **Reply #134 on:** January 24, 2015, 05:17:02 pm »

1/2 watt is fine. Would be fine on the second tube plates also.

lego4040 · « **Reply #135 on:** January 24, 2015, 05:28:23 pm »

hopefully I can stay awake and make this parts order tonight, been a long week at work that just ended an hour ago. Hey how do you like your weber in the tweed deluxe you built. I'm reading up on their 12" alnico. There are 3 vintage models that looks nice

sluckey · « **Reply #136 on:** January 24, 2015, 05:33:31 pm »

That weber is in my leslie now. There is a Jensen in the TDR and 5E3 now.

lego4040 · « **Reply #137 on:** January 25, 2015, 08:02:11 am »

Ill look at them Jensens as well, I have a 12" Guitar Warehouse speaker in my one combo now. I couldn't pass it up for the price and it is a nice sounding speaker

lego4040 · « **Reply #138 on:** January 25, 2015, 02:11:38 pm »

In searching for a speaker, since this amp is approximately 20 watts watt should I look for. A Jensen P12R is 25 watts, a P12Q is 40. I understand the Q will need to be driven louder for it to break up but will give cleaner headroom till it starts to breakup. I guess it's a mater of choice

lego4040 · « **Reply #139 on:** January 26, 2015, 04:13:12 pm »

As for the cap board, I'm thinking about putting the four mains inside the chassis rather then on the back. I like the way Doug does his inside. That that size chassis and the board not being huge I think I'll have a ton of room.
Maybe once I get the chassis I'll get a small cap board in the same natural turret board material. I havent heard back from Mecury Magnetiics yet..

sluckey · « **Reply #140 on:** January 26, 2015, 04:38:02 pm »

I have a Jensen P12N in my 5E3. Sounds good to me. I would build the amp and then try every speaker I have before buying an unheard speaker. You may just already own your holy grail.

sluckey · « **Reply #143 on:** January 28, 2015, 04:46:25 pm »

Tone Tubby wasn't even a thought when Eric and Carlos made their tone. Back then hemp had a much HIGHER purpose.

Willabe · « **Reply #144 on:** January 28, 2015, 05:03:00 pm »

I have a 12" Tubby Tone alnico hemp cone 50w(?). I like it a lot, but they cost big $$. I've been using it with my 5E3 and 5G9. I have a 25W TT alnico here I haven't tried yet.

It's a fatter sounding speaker then my 15" WGS alnico, has more mid range. Nice bottom and top end, IMO.

What I've read about the theory behind using hemp instead of wood pulp for the paper cones is that because hemp derived paper is supposed to be stronger than wood pulp derived paper a hemp cone can be made thinner than a standard wood pulp cone.

So a thinner cone can handle the same power and because it's thinner it's supposed to be more pick/touch sensitive than a slightly thicker paper cone.

But, what they don't tell you is how much hemp their using, %, when mixing it with the standard wood pulp paper mix.

So it may all be hype marketing.

Eminence makes a good # of great sounding speakers that guys here love the sound of. And they are much more reasonably priced per watt.

Hard to beat them.

Your Guitar Warehouse speaker might sound great in the 5G9.
