Normal channel ab763
« on: September 03, 2018, 03:08:59 am »
Just thinking of building the normal channel of the ab763 deluxe amp with some left over parts and wondering how to do the bias pot without the intensity pot connection?

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