Re: How to repair a fine coarse tuning poti ?
They work in principle, but they both do not allow a stable result in frequency.
If I set coarse, and then tune with the fine knob, fine influences the coarse.
I think there is some dirt between the axles. It became better some oil.
Still there is a lot of hysteresis.
I believe it is necessary to look inside the mechanics....
