Greetings to Ed and the list:
Ed, you wrote: <snip> " The S-meter is described as 0-200 Ma, ..."
I am having a rough time with this number. I don't think the whole
radio draws more than 200 mA total, except for the filament circuit.
Therefore, I am at a loss wondering where in the radio did Hammarlund find a
circuit with a 200 mA change in current with applied signal strength.
Is it possible that this may have been misread and the actual meter
movement is 200 uA (200 micro-amps)? If so, this will make a big
difference in S meter readings if you go with a non-original 200 mA meter
according to your spec above.
