Hello everyone, My peavey 5150 212 combo stopped working a few days ago. The post contronls didn't work and the volume was really low. Plugging my guitar in the effects return didn't work either. First I checked all of the tubes by replacing them and checked the effects loop with a jumper. Then I saw that tube 3 and 4 weren't glowing. All of the fuses are still good. I found a few resistors which don't really look too good, see link below. https://drive.google.com/file/d/0B3N2_Ue1j6msLUNlUUl5amNlTTg/view?usp=sharing The damaged resistors are r110, r111, r116 and r117. They can be found on the schematics in the lower left corner, just right from the rectifier. Can this be my problem? https://peavey.com/forum/download/file.php?id=14233 (the schematic) Thanks!
