One of the important changes made in the RCA-Rider Chanalyst 162C was adding a stand-by function to the power switch.  That served to preserve the life of the 6E5 indicator tubes by cutting off most B+ to the tubes except for a feed by way of a 100K ohm resistor.  Most earlier models have much of the upper green image on the tubes worn out except for the lower portion which is activated only by the four channels. I will upload a copy of the 162-C, code 643 schematic which shows the stand-by function.
