I Bought a few used TK880s, I could use a little help:
1. Does anyone know why C152, the 1000uF would be removed?
2. The I/O (Power switch) has been set up to turn on and off the audio amplifier (I believe this is a power saving move for use a porta-peater). Any information on returning the I/O switch function to power On/Off would be appreciated.
