Reverb for project valve amp
Hi there.

Looking at getting myself a project to work on over Christmas.

Amp Maker: Guitar amp kits and parts :: Guitar amp kits :: Double Six switchable power amplifier

Want to add a valve reverb unit in it like on an old fender or vox amp. Does anyone know any kits to use or have any advice?

I have a Peavey Valverb reverb & tremolo I just put in the effects loop.

Weber has an IC tremolo kit for tube amps, but not a reverb, though they do have a "general purpose gain stage" add-on sub-chassis that would do nicely.

I'd get a kit with a reverb. You won't fit the extra valves in the kit's chassis so you'll have to have separate chassis for the reverb's circuitry, match the B+ voltages, and fit the tank in your case too.

You could maybe fit the accutronics belton brick in your kit. It's a reasonably good digital reverb made by the guys who make spring reverb tanks in an attempt to get that same sound. I like it, but many don't. Support circuitry is pretty small, but solid state. It won't thunder when you hit the amp though.

Or you might do what most tube amp makers do (Peavey/Laney/Marshall/etc.) and add an SS reverb circuit there.
Here's how Fender does it: slams the reverb circuit between the full tube pre and power amp.
No big deal, after all it's an effect.

http:// at the construction manual it looks like there is room for two 9 pin sockets. I think I would use the circuit from a fender aa763. I would add terminal strips near the sockets and build it point to point. and then implement the circuit the same way fender does

There's some schematics on The Valve Wizard
and I know I saw lots more...
