Sorry for slow updating on this. Anyhoo: have dumped another half a can of contact cleaner into the switches but no result.
Tried connecting a signal to tape input but not a sound.
Measured the IC:s as suggested and got:

IC 3
Pin 14: 13,7v
Pin 7: 1,3v

IC 2
Pin 14: 13,6v
Pin 7: 1,3v

This looks not right, right?
Should be +14,3v and -14,3v if I interpret the schematic right?
What now?
Thanks in advance for suggestions for further troubleshooting!
