V-M 560A problems

[Captainclock]

I worked on one just like this last year and the one I worked on had a bad 5Y3GT Rectifier tube and an intermittent 12AX7 preamp tube socket that I had to clean the socket pins on because they had cadmium disease and I relubed the motor bearings but that was it because the changer mechanism still worked fine yet. that clear plastic button that lights up on this unit is actually an external activation switch for the changer.
