Please check the tube line up of this model. The US 6K4 linked to the model was a subminiature triode registered in the late 1945.

Many thanks,

Emilio

We can remove the question mark from this thread. The solution was found by Achim Korn. The mistery tube seems to be a 6K6, also used in other models of the same manufacturer.

Many thanks to all.

Emilio
