3C36

Information - Help 
ID = 39491
       
 
   
Tube type:  Transmitting Triode, air cooled   UHF 
  Ca. 1925 up to 1945 extraordinarily rare. Production was less than 100 items. ****
Identical to 3C36 = R1001
First Source (s)
05.Feb.1946 : Electron Tube Registration List 473

Base COAXIAL in general (X..)
Filament Vf 6.3 Volts / If 2.8 Ampere / Half indirect
Description

UHF coaxial power triode. Extremely advanced design, capable of operation in the range from 500 to 1500MHz. It could be operated with press-on heath radiator, either a finned one for forced-air-cooling or a water jacket for fluid cooling. Quite exceptional ratings claimed in the datasheet.

  • 200 W plate dissipation forced-air-cooling, 500 W water-cooling
  • 2000 V max anode voltage
  • 50 A peak anode current, 0.8 A RMS current
  • 100W typical RF output at 1000MHz, 250W at 750MHz.

Likely developed for some airborne navigation or radar-like system canceled at the end of the war. Registered in February 1946 together with the 3C37. No known use for both of them, even if the second one was advertised in the same year. Indeed the only sample of 3C36 today existing is that still marked with National Union developmental code, R001.
