RCA portable insuffient B+ Boost

[hobgoblins]

Hello all!

I am new and I was wondering if you could help me. I am working on a RCA portable EJ507J CTC22 and the B+ Boost is about 480 volts it should be 720 volts. I get a picture but the horizontal is half the size. Like I have a short in the horizontal winding of the yoke. I used a ringer on the flyback and the yoke and they both check out fine. When I first turned on the set after I recieved it and I found a puddle of wax in the flyback cage after I ran it for 20 minutes. I can supply more information if needed. If you can stear me in the right direction to solve this problem I would be gratefull. Also could someone explain the 2 damper diode in parallel.


Thanks
