Hello guy's,
Have been working on this K130 console,and found the right capacitor for the electric tuning motor.
Installed it and the motor now works.
However if you push one of the station pushbuttons it will just motor across the dial until it hits the end of dial,then the motor keeps spinning but it does not reverse.
Is there some kind of sensor that reverses the motor at the ends.
Don't know how the station pre-sets are set to specific stations either.
I also noticed that the chassis gets hot to touch over in the corner where that long strip resistor is mounted with the R24,R25,R26 and R28 resistor hookups are.
Is it normal for these to get hot?
Have replaced a bunch of wiring on this set.Now it looks like the tuning eye tube wire harness is bad and the tube socket is brittle.Not sure if I can get that apart without breaking the plastic socket.
Anyway,If anyone has any suggestions for any of these problems,it would help.
Thanks
