Add-on tank reverb and loop
I am in the process of doing an HRM champ and don't have room for even a 1 tube reverb or loop. I had a 5 x 7 Hammond box and decided to try to build a no compromise tank reverb and loop using a Fender stand alone reverb power transformer and tank transformer. This box will sit vertically against the right rear wall behind the backboard, this leaves room for a short tank on the floor of the amp. 3 tubes, 3 controls and 2 jacks make for some tight design but here's what I came up with - the build is in progress.....
EDIT: updated layout and corrected errors

Great Thanks for sharing. I'm looking forward to building one of these.
You wouldn't a schematic handy, I get a little lost with layouts sometimes.

I built it from memory but I drew this up just for you...tonelab2 wrote:Great Thanks for sharing. I'm looking forward to building one of these.

Thanks heisthl, very much appreciated. Now I can get things sorted.

Would this go before the input of the amp?
Re: Add-on tank reverb and loop
This goes from preamp out to poweramp in. The build I'm working on right now to use with this box has 2 DPDT front panel switches labeled "Reverb" and "FX". These swiches are chained together so when both are off the signal stays in the amp. When both switches are on the preout feeds the loop in and the loop out returns to the amps "Reverb" switch which then routes the signal to the reverb in and the reverb out comes back to the poweramp in. This method puts tank reveb on the FX, but if you wanted reverb first you could switch the connections (the switches would be labeled wrong). I should have this build up and running today or tomorrow and I'll post pictures and status then.

Guys I think Henry is way too busy to reply his RedPlateAmps are taking off like crazy and sounding fantastic.

I can Imagine how good it sounds if Henry is building it.
Nice modules to answer any need with tone.

Re: Add-on tank reverb and loop
Built a version similar to the original, but in a little larger box (8"x6").
The larger size box was used to accommodate the addition of the output level pot that is found in the Dumbleator.
Reverb tank used is a 4AB3C1B.

Re: Add-on tank reverb and loop
Anybody ever find out if this worked or sounded good? Just realized I have enough spare parts laying around to build one.
