Found HOT Q502 shorted and 2.5a pico B+ fuse open . Replaced HOT and
fuse,plugged in and checked standby volts. I only had +15V at coll of
HOT, but the +9V and +5V stby was good.Did not find any shorted small
transistors or diodes.Turned on,heard a rush of HV and SSSSSHHHOOP.dead.
HOT and pico fuse bad again. Pulled the scan cap C505 (10nF@1600V)
measured OK. Any history on this? Phil
