EABC80 / 6AK8 und 6T8: Unterschied

Die EABC80 / 6AK8 hat eine bessere Abschirmung zwischen Heizfaden und den anderen Elektroden, besonders zum Steuergitter der Triode, zur Unterdrückung von Brumm.

Dazu werden bei der EABC80 die Katoden von Foben   Hgeheizt und die Röhre ist dadurch  höher. Ansonsten sind EABC80 und 6T8 gegenseitig austauschbar.

Dear Ernst,

 

I would like to satisfy his request, in fact he would have a lot of taste in doing the upload of the tube for Rmorg, but it happens that I neither have the picture nor the respective tube.

It can be that later manages to do it.

 

Best regards from,

  4 Dear Júlio
OK, but the 6AK8 is just missing the schematic you published here (above).
Can you put it up?
Thank you.
