Can anyone direct me to the best place to get help fixing my Blues Jr III Reverb not working. subbed a 9fb2c1b to see what would happen and I got some reverb. Bought a new MOD pan, no good Went to billm to read up on it and got some direction. I did the test where you put your finger on the jack for recovery and listen for the hum/buzz and could hear it get louder as I turned the reverb pot. Test point voltages are off and on pins 4 and 5 of the op amp I have -15v on 4 and 0 (nothing) on pin 5. Replaced op amp with a TL074 and no good. Now I do not get the hum on the black recovery lead to the reverb tank. Amp kind of barks when you hit the switch to off position. (don't know if this might be related to my reverb problem) Not sure where to go next. Any help?
