I've got a magnavox D2935 that, admittedly is in rough shape. Despite
that it is a great radio, I really like the audio quality and it can
resolve a lot of stations my 7600gr misses. So I want to keep using
it. But there is a problem. Suddenly, after listening to the radio for
a couple of minutes the tuner pops back to 520 khz. I change it back,
it's good for a few minutes, then wham, right back to 520. This just
came on all of a sudden last night while enjoying a musical respite
from the usual Radio Habana Cuba blather.

Any ideas what might be happening, or better yet, anyone feel
comfortable enough with this model to attempt a repair?

Thanks.
