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.
