The Amp Garage

Hi Gents, I built an Ampeg Reverberocket R-12-R style amp with the octal tube driven reverb and it sounds great. One of the locals played it and wondered if I could build a stand alone version of the reverb that he could use with his tweed Bassman. I was thinking of doing a Revibe with the Ampeg rev...

Some Pics - may be some slight differences.

I think norburybrook was talking about later in the circuit? The R22 resistor sends part of the signal to ground. Using a larger resistor for R22 would send less signal to ground and maintain more (dry) signal voltage for the mixer stage.

Maybe add a trim pot in line with the 68k, tweak to taste, then replace with a fixed value?

I prefer less filtering, as well, so I will probably do the same. Thanks.

I threw together a schematic of a 50w version from Taylor's layout. I'd appreciate any comments, critiques, etc.
(Edit to correct tube type and adopt Guy77's recommendation concerning filter caps.)

Well, sorry, dogears says you have to change it back.

I did have that one, Tony. Sorry, I just picked one out of the folder. I didn't know that particular area had been revised. It's hard to keep track. Love the layouts, though, excellent work.

You're correct. By that schematic, when the loop is not being used (nothing plugged in) the circuit in question is bypassed.

However, Tony's layout shows the opposite as Dogears stated:

I was listening to some of Peter Green's Fleetwood Mac today. It's amazing you never hear this stuff. It's all blues - nothing like the post Peter Green Fleetwood Mac. Worth a listen.

Do you guys have any build shots, gut shots, eye candy, etc?

Here's a thread talking about some layout differences with a schem - looks like the same one you found.

Yeah, I caught that on XM Bluesville and thought I had to share it.

Take a listen to 8. Don't Turn This Child Away From Heaven.
