Yes, Bruce, I am quite pleased at how things have been progressing and I do hope the ethers tidy up over the Winter season enough to improve the listening experience.
I have been able to confirm that the R58A resistor in my Remote Receiver has packed it in. It is a pair of 1.2M Ohm resistors actually. The Master Parts List provides two options of a single 600K Ohm or the aforementioned pair, but of the three receivers I have for inspection, all are equipped with the paired arrangement. I wonder if the single resistor configuration was very early production, or very late?
In any event, both of this particular pair are fully open and toast. I have tracked down a supply of carbon composite resistors that match the factory originals and once on hand will swap the offending pair out. Took a while to track down the location of the R58A on the chassis but did finally find them, with the help of a nice bright LED torch, sitting on the long terminal board on the underside of the chassis. See the attached photograph. They are the pair immediately right of the empty pair of terminals on the right half of the board.
I think I may take some time to ID all the other components on this board for future reference. Particularly the resistors. In poor lighting, the background colour and the aging of colours can make it a bit of a challenge to spot the typical resistor colour codes easily.
