These are old machines, and TEAC's soldering was never top notch. I've
repaired many a TEAC cold solder joint. From what you've said, you've done
all the basic work with pluggable items without success, so...
If you're an old hand with a soldering iron, I'd suggest first
resoldering/replacing the shielded cables off the playback head. If that
doesn't help, resolder every suspicious-looking component joint (sigh) on
the preamp board responsible for the low-level signal. If that still
doesn't work, see if you can capacitively load down (very lightly - a
finger will do) the semiconductors in the preamp circuit until you find one
that might be rectifying the RF, then replace it.
Shucking radio signals is really a problem in old equipment.
