Found that there is 0.0 volts at "C" and working backwards, found 0.0 volts at "F". Have 373 volts at "A". Thus, it is now obvious that the 1K, 10W resistor has failed. Have a new one ordered from Antique Electronics Supply. Will report back when resistor is installed. Thank you Hangman for your guidance. Having the correct schematic is very helpful.
