Panasonic CT-1310M keeps blowing horizontal output transistor

1) THOROUGHLY clean up tape mess
2) replace HOT & mica, compound each side & tighten evenly
3) remove B+ fuse & replace with dim bulb tester.

Now run the set watching it. The pix may be a little small and / or have
hum bars. Turn off & feel HOT every 5 mn for heat. Should be just warm.
Over current will brighten the bulb & lower HOT current. If that happens look
for a symptom, burning etc. If it runs an hour or 2 its probably OK.

This is old school BUT I remember going to a GE seminar @1975 & they
taught it for the same problem on the new SS sets, blows HOT instantly.
