Description

A 6F5, which is normally an Octal tube, here with a German Y8A Steel-tube base, as replacement for the triode unit of the ECL11 in France.
For the output unit of the ECL11 an additional output penthode 6M6G was required to built in.

To fit into the Telefunken steel tube base Y8A, an extra thick bulb had to be chosen for the 6F5_Y8A.
