Been a long time since I saw one of those but I think they used 955
acorn tubes for the RF.
Don't know about the other tubes.

Bob - Had a TR-4 in the early 1950s. Used a HY75 free running
oscillator modulated by a 6L6. The receiver was a superregen which was
an acron tube, 955 I think. But has been a long time and can't remember
the ohter couple tubes in the reciver.

Enjoy a unique piece of ham history. They were very popular during WWII
being used as the basic radio for the WARTS nets.
