The 9-160 was a WALK IN THE PARK, compared to the GCS Sonys ! I fixed a WHOLE Bunch of them, for myself and others, "in the day" (Late 80's to mid-90's or so.) I ONLY had a few I could not fix. Often solder joints caused most of the problems with them. Saw a few bad B+ caps and 200 volt problems too. had ONE that would work FINE in a manual-tune set--but with the electronic tuner it would NOT tune--IIRC loss of a 7.5V or so flyback voltage line. Some bad fly's too....but overall--NOTHING like the GCS sets !! And the "startup" ckt on the 9-181 sets was not too bad---I recall a COUPLE that would NOT " Quench" the start pulse" and burn up that 1K resistor in a few sweconds, one was a bad quench transistor, and IIRC, ONE had a bad "puff" type cap. Of course--BOTH the 181 AND the 351 ATE flybacks !!
