Hey everyone,
I am planning ahead here a bit but I would like to build this as a good match for my TOS. One of the threads I found on it is here:
http://el34world.com/Forum/index.php?topic=10624.0 (http://el34world.com/Forum/index.php?topic=10624.0)
I realize this is an old build and from what I gather Tubenit has since gotten rid of it also. I have gone over the schematic and assembled my BOM. Seems fairly straight forward. Any thoughts on it or does anybody have one of these they are still using? The main question I have so far is chassis size. I'm thinking something like a 9.5" x 7" x 2". Does that sound about right?

I think you might have some challenges building that into a chassis that small? It might work? Just not sure?
Both my amps now have the FX loop on board.
I got lazy about hooking up wires to the unit then to the pedal then to the reverb pan. I liked the way it sounded but I found I was typically just putting a relay or delay pedal into the passive FX loop jacks. Again, it was more laziness then anything else. If I played my amp 10 times, I was hooking up the unit maybe 3-4 of those 10 times. My amps sit in closets and I pull them out to use them. IF I had my amps sitting out, then the unit would have been left hooked up and connected all the time.
I had the FX & Reverb unit in a small head cabinet that I set on top of my amp head with long reverb wires that connected to a reverb pan in the bottom of the cabinet.
I would not build another FX & Reverb unit for a higher gain amp like a TOS. I would build another one for a clean amp or something with moderate overdrive like the HoSo56.
I would lean towards just building an active FX like in reply #5 of that thread. The tube and the PT were inside the chassis. It was small. It looked good and sounded great. There are some really good reverb pedals out there now. I use one of these:

I read some good reviews of the Hall of Fame reverb unit also.

On higher gain amps like the TOS, I think delay tends to sound a little better then reverb, IMO. IF by chance, you have a reverb pedal already, I'd probably advise skipping building the reverb/FX in favor of just a D'lator type FX and then use a reverb pedal into a delay pedal which I think sounds incredibly good.
I have owned a Wampler Faux Echo, a Boss digital delay, currently own a Carbon Copy ................... and my favorite delay pedal is easily this
Moen Pretty Dolly which is the cheapest of all of them and has had the warmest tone in my amps with no high end "chirp". It does not have tap tempo like some of the other pedals though. Sure has a sweet sound though! I think I only paid about $50 for it.

Awesome. Thanks for your replies. I own and use the Hardwire DL-8 delay pedal. I love it and it does sound great. It is also the only pedal I have in my fx loop. With the TOS I have truly embraced the fact that don't need many pedals. I have looked at several reverb pedals including the Hall of Fame. I am employed at a retailer for such things so I can get a great (cost) deal on them. But something just appeals to me about a standalone type verb. I thought I would always go the 6G15 route but then I saw this. I could always use it with future, cleaner, amp builds. :wink:
The post #5 in that thread is the D'Lator? That looks like another great option and since you have never steered me wrong in my progress I am inclined to seriously consider that as a somewhat easier, smaller project.
Couple of question though. Let's say I get a 12" x 7" x 2" chassis. Why have all the builds I've seen for this put the xformer and tube inside? Just to make it more compact? I will put a BOM together for this and compare them.

Yes. I gave this unit to DaGeezer after I built my two amps with active FX on board. He expressed liking it quite a bit. It was super quiet and made a wonderful master volume, IMO. Probably should have picked a prettier color for it.

BTW, I have changed one thing on the active FX loops that I've done the last few yrs.
I've added a 470k to make it sort of a paralleled loop. On some of them I've also added a .001. I like how this sounds more and particularly if you have a digital delay in the loop, this 470k helps remove or lessen some of the high end "chirp" that one hears in a digital delay.
Overall, it adds some warmth and there is still plenty of delay left to dial in on the pedals. So audibly, I am hearing the same amount of delay but just warmer in tone, IMO. I do NOT have a toggle switch on this with my amps but you could install one to have both series and parallel delay.
