Ok, the TV chassis's making great progress - we got sweep, we got SOUND! And that means video on this set. The sweep circuits seem to be locking up nicely.
Uh oh! The HV is only 7kv! Not enough to light up that big screen. A little diagnosis found a bad yoke. The replacements, FWIW, are listed as:
Stancor DY-7
Merrit MD70F
Motor roller: 24C792699 or 24K792714
It's got a bad section in it (open).
I have a Sparton that's less than wonderful, which lists the same yokes as replacements, and it's yoke even looks the same. I'm thinking of thefting it for parts (it's a less than amazing TV, and pretty plain Jane). Assuming I can't get a 'fresh' replacement yoke.
This brings up an interesting question - did Motorola, etc, sub these yokes out to Stancor, etc? or wa the TV paerts demand that great back then that third party companies could bother with the effort making these yokes? How unique IS a yoke, anyway? Are they pretty much all the same?
