Oh, these little Motorolas are cute but infuriating. I have one with a typically shot 7JP4, and to add to the fun, it randomly dead shorts or blows out rectifier diodes in the PS. No rhyme/reason to it. It's not an HK short on the CRT, I once put a transformer supply to the heater and gave it about 15V and got a respectable picture.
I'd say next to the Predictas, these things have to be the worst sets out there to get going, but they're so darn cute....
Vertyical lin troubles got me, too. So I'm getting some ideas here on what to look into when I decide to tackle mine again.
