GE BT-50 Series

General Electric was the manufacturing arm for the companies building early broadcast transmitters. Westinghouse was heavy into the control circuitry and RCA packaged a lot from these two.

The GE 50 kW Series:

BT-25

The first 50 kW unit by GE had the model number BT-25. We are still trying to find out why.

BT-50A 

Bill Frahm says:  KOA, KNX, WSM  had versions of it. Seems to me the 
        A1 was 480 V primary - A2 was 4400 V primary - A3 was 7200 V primary. 

I had the GE BT50-A1 in Boise, built in 1964 -65. Our A1 had the 4400 v inductor on the primaries of the three 480 v pole-pegs.

Other stations using the GE transmitters include KRLD, KPOL, WLS and others

KCBS, San Francisco
  

BT-50B

KPOL, Los Angeles  (BT-50B???)
  

BT-50C
The 50C seems to have been an upgrade from the 50B, the BTC-50-C was built in Canada.
