update for others reading this.
when i power up, at the + side of C57c filter cap & 1kohm resistor R38 i experience this.....
radio warms up and meter shows voltage ramp up to about 325v, quickly the voltage ramps down to only 55 or 60vdc.
radio has no output.
if i leave the set on for more than 20 seconds the 1kohm resistor will overheat.
terry,
I disconnected the two wires at C57c.
my voltage settles in at around 230vdc when i leave this branch open that feeds pin 5 of the 6c4.
I do notice now that what i thought were dog bone resistors are actually CAPS!!
