NFB unhook UL Fender
« on: April 03, 2017, 01:39:06 pm »
Where does one go to disconnect NFB on 70watt PR? Sounds great, very compressed...want to hear without. Only "mod" I see is wire from pull out to reverb (1/2 of switch) has been removed. Is it 820 R 1watt? Thanks!

I would just disconnect from the speaker jack. This will also kill your line out jack, but it's just a test.

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