| Descripción |
Bill Eitel, W6UF and Jack McCullough, W6CHE did the engineering work at Heintz & Kaufman in the early thirties for this tube which was designed to compete and surpass the RCA 852 tube. They later founded Eimac because Heintz & Kaufman were not much interested for the HK354 and the two engineers found the way to design very modern transmitting tubes by developing the HK354 in February 1934.. Their first product was the 150T.
Thoriated-tungsten filament, tantalum plate and grid. Amplication factor 14
