Fellow Radiophiles:

Are there any surviving mechanical drawings for receiving tubes?

This is the kind of drawing that would have detailed dimensions for all the electrodes. The distances between the electrodes are as important as the the dimensions of the electrodes.

Regards,

-Joe

Dear Joe

In the old textbook written by Prof. Barkhausen “Elektronen-Röhren” Volume 1, 4th Edition (1931)
I found some drawings of the internal structure of triodes used in this period.

 

 

RE034RE134

 

RE064RE144

RE604

REN1104

In the 11th Edition of the same publication dated in 1964, more contemporary tubes are depicted.

EF80

ECH81

For a better resolution I attached the same pictures below.

Kind regards.
