Hi Jeff
the capacitors replaced were high ESR ..C841 blew out again after I
replaced
Q801 and Q802..replaced it with a 160 volt rating but it gets hot after
a short
time..Set comes on but is in on the sides..Is the rectifier D840 fast
switching
or regular diode Do you have the voltage rating of the zener D841
thanks
Alvin
