RCA K130.New problem.

Sean Wrote:There are no limit switches on that tuner. The large metal contact disk on the back of the tuner is separated into 2 segments with an insulator separating them. Depending upon where the selected preset is and where the tuner is when you select that preset, one section of the disk or the other will be selected. These segments determine which direction the motor turns to get to the correct position on the dial. Read page 15 of this service information on how the mechanism works and how to set it up.

When the dial is set to the station you have selected by its respective push button, the pin contact on the back of the tuner should be on set on the insulator. You may need to pull the contact pins out and file them to a point so they don't overrun the insulator as the motor is moving.
Hey Thanks Sean.
Will look again and see whats happening.
Right now it just travels to one end or the other,and then the slippage of the tuner cord keeps it from breaking anything.
You would think it would reverse itself after hitting the end of the travel.
Do you know if it's normal for that long strip resistor mounted to the back of the chassis should get hot?That area of the chassis will get hot after playing for a while.
Have a great day Sean,

Well,tried removing pins and putting a point on them to no avail.
Still skips right past the gap in the disc.
I suppose I could try re-wiring the contacts.Have found lots of bad wires on this set which I have had to replace due to crumbling insulation.
Otherwise,I think I will disable the electronic tuning and forget about it.
Thanks
