Managed to do some serious de-dusting and cleaning of the unit, and have listened to it for a while. I'm suspecting that the 12DT8 in the tuner that handles the FM portion of the signal is going to have to be replaced, the FM signal tends to flake out a bit, and come back when I tap on it.
One thing that's odd is that the stereo has one woofer, perhaps an early edition of a subwoofer
. It tends to bottom out on bass notes even on non-bassy music, unless the bass control is kept about halfway or less. I'm thinking the original speaker might be a little bit brittle. Might make a small project of putting all new speakers and crossover caps in it.
Uh oh, that's where it begins, isn't it?
