Here is the Amp board. It is a corroded mess in some areas. Also one of the large 7500uf caps measures about 6900 the rest are over 7100uf.
I also noticed that TR 343 broke a trace underneath that I had to repair. It might have not been making a very good connection. I replaced it but it might have been jarred loose during all my testing .
But this is the negative TR I believe. I'll clean up the Glue and measure the resistors and check all jumpers that might have been compromised
by the corrosion.
The glue near the TR's that power the EQ board is much more burnt compared to the other Large cap glue.
I wonder if those caps were getting hot too and if they help power that +/- B1 line
The Pics.
Denatured alcohol is not cutting it, I think I need to use acetone here.
