Zeitbestimmung!

Ist die hier gezeigte Röhrenschachtel aus den 20er oder frühen 30er Jahren?

Freue mich auf eine Antwort von den Röhren Experten

Lieber Wolfram,

Ja 20er oder frühen 30er Jahren!

The earliest is 1925 and the latest production advertisement that I can find is 1931.   

These low voltage tubes were not used in many radios, of course.

Best regards,

Roy
