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?
600k is not one of the 'preferred values' in general use, so while it might have been the designer choice in practice it would have been a pair of 1.2M resistors (which are in the E12 preferred value range). The closest single E12 value otherwise is either 560k or 680k (all values +/- 10%. A pair of E12 resistors meant one less specialised stores item (that may just have been used in that receiver) that needed to be carried by workshops.
