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?

Jrb25,

Since your tuner is solid state and draws little power, I'd suggest you just keep it powered up 24/7. Eventually its temperature will stabilize, and I'm guessing you'll see little or no drift from that point on. I keep mine turned on all the time for that very reason.

Thanks for all the suggestions. David, I'll try leaving it on for awhile to see if that helps, thanks.

Jeff.

I have 3 Sansui 9090DB receivers, all of which drift off station after about 15 min. I suspect a capacitor changing value when warmed up. Obviously a Sansui design flaw, or poor line of caps. Again, maybe a transistor is changing value when warmed up. Can anyone advise me where to check? I have a schematic I downloaded a few days ago. Others must have experienced this as well. I live in Phoenix, Az. where the air is dry, and is why I suspect a capacitor.
