Hello,
I just finished building modified AA964 by using 1946 transformers from an old see burg amp and it sounds amazing. Being Catodyne PI it does have a lot of mid range but I like this vintage feel to it. For my next project I would like to transform my old Bogen Challenger amp that used 6878 tubes into Deluxe Reverb blackface amp, but without the Vibrato channel.

The first question I have - Does anyone have a schematic of modified AB763, without the Vibrato but with the reverb?
Second question is - on OT center tap Bogen has about 460V, but the AB763 about 420V. Will it work with 6V6 tubes or should I switch to 6L6 instead?
The last question has to do with my reverb can. Several years ago I got it out of an old Hammond organ. Will it work for this Fender type amp?
