RE: Accuphase 101 T tuning
Posted by fredtr on August 15, 2016 at 18:03:10:
Not typical, I had two of them, neither exhibited that problem.
Alignment alone, probably won't fix it. It sounds like a thermal problem, a component changing value as it warms up. You might be able to identify the component with cold spray, but you will need to spray very little and use shields (cardboard is fine) so that you can cool one component at a time. Tuners with thermal tuning problems are more difficult to isolate the component than other problems/equipment because the spray cools too much and condenses moisture which can also detune temporarily.
If you decide to live with it, and you mainly listen to the same station, tune the station in warmed up, then turn the tuner on earlier than the other equipment and let it warm back up.
