Long story short: I bought this amp in 1975 and from my research the nearest I can tell it was manufactured around 1968.
I last played in 1983 and since then the amp has been covered and stored in my garage. I have only got it out a time or two since then and it worked fine.
Got it out a few days ago to start teaching my grand daughter how to play and of course, the amp does not come on. I get power and all the tubes seem to have power. I only get a pop in the speakers when I switch the standby switch.
I am taking the amp to a repair guy tomorrow and I wanted to take him a schematic but I can't determine which is the correct schematic from my searches on the web.
I found the following schematics on the web:
- Showman-Amp AA763 Schematic
- Showman-Amp AB763 Schematic
- Showman-Amp AA568 Schematic
I can attach the .pdf files for those schematics if needed.
Can anyone help me find the correct schematic for this amp ?
I attached pictures in an attempt to help identify which schematic is correct. I can pull the "guts" out and take more pictures if necessary.
Since I am electronically challenged
- Any help will be greatly appreciated.
