I have an AB165 amp 1968. It's rebuilt stock. I tried the AA864 normal channel mod and liked it but I also like the AB165 normal channel. How can I combine these two amps? When I tried the AA864 normal on the otherwise stock Ab165 I got a lot of hiss whenever the volume was up on the bass channel. I switched back to stock and all is well. Does anyone have a schematic for something like that?
Thanks,
RK
