[Milsurplus] PRC-47

[Don Reaves W5OR]

H.O.,

From "Transmitting Tubes for Linear Amplifier Service", a paper presented 
at the the 1956 National Convention of Institute of Radio Engineers:
zero-supressor-voltage type beam pentode
PL-177  Fil. 6.0@3.3A 75W Max. Plate  Class AB1 Output 96W at1KV, 
140(ICS)@1.5KV, 200(ICS)@2.0KV.

If Collins designed the transmitter for low duty cycle that could explain
running 1500 volts on the plate!

Sorry I don't have a full data sheet from Penta.   

Sibley says PL-177 is 4-125 format but all glass,
alternate to Westinghouse 6549
