Larry, disregard that, finger slipped look for a bad R6234 or R6242 620 ohm
2 watt off emitter or Q6208 if app to your chassis. ctc169bg5

Hi Guys, this CTC169 BG is giving me fits, the Standby Regulated B+ goes
up to 275 volts, of
course the original problem was "dead set" I`ve changed U4101 ,
C4102,C4104, C4108,
C4118, & CR4118. CR4101 & CR4106 are within 1/2 a volt of each other,
Can`t think
of anything else that will cause this, Raw B+ is 157 volts, U4101 pin 16
is rock steady at 10.8 volts
any ideas would be greatly appreciated, Larry E
