[ARC5] BC-AS-230 Transmitter, part 1 - tube adapters, general clean-up, q...

[WA5CAB--- via ARC5]

This is a phontom antenna, not a dummy load.  I have a number of different 
WW-II vintage phantom antennas and most have or appear to have wire wound 
resistors.  Only one that I know of for sure doesn't.
