Did you finally get it fixed? If so can you post what was the problem?

Unit came in dead, H-out transistor shorted, Removed transistor and B+ came
up to 130 V.( must be a pretty healthy power supply) Check caps and ring
flyback ok, Installed a new transistor and set came on and looked good. Let
it play for a few hrs and turn off for the night. Would not come on the next
morning, H- out shorted again. Replaced flyback and trans, set worked good,
played a few hours, I turned it on and off several times, everything work
ok. sent it home. set worked Fri night , all day sat, and sat night, Would
not come on sunday morning, Cust stated it was working good when she turned
it off sat night. H out is shorted again., Looks like it must be shorting
at turn off or something while its off, Anyone got any ideas on this one?
