zenith 20bc50 problems

[daduke]

spent last hour checking everything i could i cant find my good multimeter to save my life and the backup isn't exactly up to my needs. i pulled the hv rect. took 20 minutes as it seemed glued in finally popped out taking part of the fly back board with it :/ socket is immaculate far as i can see. only sign of arcing is on a resistor that ties to the focus voltage feed to the crt. the resistor is nowhere on my schematic ( original zenith) or the one i recieved from bill (sams) though. i checked the vertical output xfrmr as far as i can tell everything seems fine. i have neither a tester or a spare tube for the 6jc5 though i can say like every tube in this set its original. not that that means much.
