Preamp only AB763 single channel
« on: October 30, 2017, 08:21:23 pm »
High folks, Just wondering if anybody had any input or schematics for a an ab763 Hoffman board that would be used as a preamp only, going into a solid state rack amplifier. I was hoping it would have reverb and tone controls. Also, in such a build I guess I could use a smaller power transformer since there will be no secondary amplification. Maybe even possibly a switching DC power supply? Thanks for any input-Mike

Here's one...
A schematic, layout, and hi-rez pics are very useful for troubleshooting your amp. Don't wait to be asked. JUST DO IT!
