[Milsurplus] AN/SRT-4A Marine Transmitter

[Bruce Gentry]

Was the transmitter made by Westinghouse?   Their broadcast transmitters 
from the late 1940s had a good deal of the wiring in lead tubing. As far 
as using resistors to drop all the B+ from one source, many older 
Western Electric transmitters did that as well.
