According to the circuit Board the + Voltage feeding those resistors is +340 volts.

According to the resistor color coding on the 2 2W carbon comp resistors you're referring to are supposed to be 68k Ohm resistors and then there are 3 green wirewound resistors on the same board that are 27k Ohm 3W power resistors which all measure within spec yet, but the 2 2W Carbon Comp Resistors which are supposed to be 68k Ohms are measuring only 16k Ohms or so, so it sounds like those carbon comp resistors need to go bye-bye, because they are WAAAAAYYYY out of tolerance.

Probably what I'll do to replace those 2W 68k Ohm resistors is cut them off on either side of the resistor element casing and then solder a new one onto what's left of the wire connectors above the board so that way I don't have to worry about risking damaging the circuit traces underneath the board, since they left about a 1/4" of wire lead above the board surface.
