Accuphase 101 T tuning

 Thanks for all the replies about leaving my 101 T on all the time.

The reason I asked about this is that when I turn the tuner back on in the morning, I have to re-tune it. If I leave it on its fine.

In order to re-tune I have to make sure the volume is down because of interstation noise, and the tuning is so sensitive.

Will an alignment solve this problem? Or is this typical?

Thanks

 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.

 Thanks,

Yep turning it on early is a solution, but I do listen to more than one station.

Another solution is two tuners in the system, leaving the Accuphase on the classical music station.

My little (really) Meridian 104 is the probable candidate for the other station since that's mostly used for news in the morning and at the end of the day.

 What's wrong with lowering the volume control a bit, temporarily pushing in the muting button while changing stations, or both?

Not that there's anything wrong with having two tuners hooked up!

 I have tried what you suggest, but the problem is that sometimes it is hard to tell when the station is tuned, even using the meters, so I have to hear the station.

Anyway, looks like two tuners are probably best, unless I can find someone to do a rebuild on the Accuphase.

I sent an email to Accutech, but have gotten no response so far.

 I agree, I'd never be able to tune just by watching the meter(s) either. I simply turn the volume down to a point where the between channel noise isn't overwhelming, tune in the station, then turn it back up to where I'm going to listen.

 FWIW...I got a reply from Accutech and an alignment is not expensive at all, other than the trouble to box up the tuner and shipping cost.

But from the comments and listening, it sounds as though I may not need an alignment, but probably some rebuilding on some or all of the boards.

As good as the tuner sounds, I am wondering if the thing to do is to just listen to it and not worry.

 You should realign using a FM signal generator, or get it done for you.

 You can quite easily realign yourself by getting the service manual.
