OK, according to my schematic, the B+ voltages on the 7M07 chassis version of the K731 the "high B+ at 40mfd cap is 139 volts. after the 220 resistor where it connects to the 60 mfd section of the cap it B+ is 104 volts. At the 80 mfd section the voltage should be 102. And as pointed out earlier in the thread, that assumes a 117 volt line voltage.
