My analog tuner drifts off the station

I have a nice Kenwood KT 615 tuner that I bought off a technician who had cleaned it up and replaced the caps. It works well and sounds great but it loses stations pretty quickly, usually within about 10-15 minutes. This happens for both strong and weak signals and I have tried all combinations of the filter and selectivity buttons with no apparent improvement.

Is there anything that can be done about this or do I need to get a digital tuner that locks on the station?

I suspect that the cable that attaches to your tuning knob needs adjustment. It can be either too tight or not tight enough.

Look for a button on the front panel that says "PLL" (phase locked loop). FM naturally drifts out-of-tune so the PLL curcuit was developed to correct this.
Hope this helps...
