[Milsurplus] HK158 transmitting tube?

[Brian Harrison]

Hi all,

Happy Saturday

I received the following inquiry about any radio transmitters using the HK158 tube

Does anyone have any info that might be helpful? (I have info on the 1920s - mid 1930s Pan Am radios but no HK tubes used in these earlier sets AFAIK today)

Feel free to contact Norm directly or just post back here and I’ll be glad to forward

(also pse cc me on any Pan Am radio-related responses, I’m still researching these :-)

Tnx and all the best,
brian

Heintz and Kaufman was a company that built vacuum tubes and equipment for the Robert Dollar steamship line.  H&K along with Globe Wireless were subsidiarys of Dollar.  Globe wireless had the shore stations at San Francisco, Honolulu, Guam, Manila and Shanghai that would be used by the Clippers on their low frequency equipment and the trailing wire antenna.
