In the mid sixties I owned a couple of German transceivers Torn. Fu. f, I believe: in the early seventies I was so stupid to throw away all the tube equipment I owned and today I cannot be sure of the model. But I still remember they used a strange crystal resonator, very similar to a glass vacuum tube, which became greenish at the resonance. In the years I did not saw anymore a similar device, nor I was able to find any reference of its data or of its operating principles.

Can anybody give me some info about this fascinating and forgotten device?

Regards,
Emilio

Dear Hans,

many thanks; for the first time in so many years I found a lot of information on this otherwise unknown device, also including its operating principle.

Regards,
