Got some more time in on the Remote Receiver after lunch today. I was able to remove the dead R58A pair of HT Meter Circuit resistors and swap in a new pair. And then the big test.
Really nice to see that circuit come to life on the meter once more. It has been running for about one half hour now and has maintained a steady 157 Volts DC.
Replacing the R58A resistor set requires turning the chassis upside down to gain full access to the required panel board, To anyone doing similar work on one of these receivers, I would highly recommend you either remove the upper front panel assembly, or place the chassis upside down on a pair of 1.5 inch wood strips.
When the upper panel assembly is in place, the upper lip of the panel actually sits above the top of the receiver chassis, If in place when upside down, the full weight of the receiver (some 40 pounds) will shove the upper panel down flush with the chassis. In doing so, it exerts all that load directly onto the two thin spring steel retainers for the two pins that fasten the upper panel in place. It is a load they were not designed to handle. Just a word of caution.
