[ARC5] History of the GO-series of USN Long-Range Transmitters

RE: the GO9 cousin, the TBW4 transmitter scheme.


I have a really nice TWB transmitter unit but no PS or  LF mate.  No big deal, but I'd like to chat with someone who may have built up an external PS and Supressor grid modulator for the unit.  I have docs on the TBW which should be enough to get it done, but just curious as to what folks have found relating to biasing the 803 for Supressor grid AM modulation.

The 1940 Westinghouse GO-9 is the most common, by far:

Even GO-9 instruction books are common.  But...

Everything else appears non-existent...except maybe this one:

  http://tlbigley.com/Cutaway%20PBY/int-06.html

The story of the associated PBY-5B is told here:

  http://tlbigley.com/Cutaway%20PBY/

The large transmitter is definitely earlier than the GO-9 one would expect to find on a PBY-5B.  Close examination of the nomenclature plates seems to show the manufacturer's name as two words...making it most probably a 1939 General Electric GO-6.  Some support for that possibility comes from the radio listing for a PBY-5A shown here:
