Agreed, but I still wanted to point that out, because many people are often confused by voltage readings that are somewhat higher than published voltages when they measure with a DMM expecting to get readings that match what was published so many decades ago. There is a good reason they don't match, and that is the 1000 ohm/volt meters in use when these radios were new.

I agree, so as a guideline the increase should be about the same percentage increase across the board for old vs new meter readings at least on the higher impedance paths.  Should give some comfort with that visual.

....or find an old RCA or Simpson meter.  

Thanks,

Mike
