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? Charlie snipped-for-privacy@bellsouth.net
