 Dougs Tremelo Mod
--------------------------------------------------------------------------------
 Hey Guys,

just drawing up some schematics for a modified Super Reverb, and I want to include Dougs Tremelo Mod that doesn't require the Optoisolator as he used on his AB763 board,

Any help would be great

Cheers
Blair

 Doug's layout of an AB763 IS a Super Reverb with the bias-trem. I mean, there might be VERY small differences in cap values (i.e., .0022uf as opposed to .003uf).

Otherwise Doug's AB763 is identical to a Super Reverb AB763 (minus opto-trem and plus bias-trem).

 Check out the Fender Feild Guide at www.ampwares.com/ffg/
Scroll down to Brownface Super, click on that, scroll through the pictures (try not to drool on your keyboard), then open the schematic at the bottom.
I think that's what you need.

 Look at the black face AB763 Vibroverb schematic in Gerald's Hip tube amp book.

I have the book cheap on this page.
