Hey Loudthud, I am getting back to amp later than usual. Had a work meeting this afternoon. Anyway, I cleaned up around the depth control(deoxit) and re-soldered a few leads on the pcb and did some continuity checking...took the jumper off and evrything seems to be OK.. I have the gain, the trem works, although it is slow to start and works only through a limited amount of potentiometer rotation. I can kill the trem with a dummy plug in the footswitch. Am giving it the longevity test now...!!! I am still skeptical about the pcb board though. There was some earlier repair work done there at some point.
Can I please clarify what schematic is the closest to this 1000S? This is a 1969 dual rect. with trem and verb. I have been comparing to the 100S schem. Is there a scematic that is more near to this amp? I am using the 100S w/reverb schematic. Does this accurately show the components of the trem-rev board of my amp? I don,t see that zener diode that is across the 1000mfd cap. It looks like that was replaced on my board as well as a couple 1K res. that I don,t see on the 100S schem. In your experience, how often is the 1000mfd cap bad? Thanks again, Rod
