[Milsurplus] output - Redux!

Mike,

The only ones I can think of would be the RAT, RAT-1 and RAV.

As all of the receivers use the same dynamotor (except for nameplates in some 
cases and the RAT and AN/ARR-2X), the B+ on the audio output tubes is the 
same.  Any chance that the output tube in the R-4 is biased to draw more plate 
current?
