In der Rundfunk-Programmzeitschrift "Die Sendung" vom 01.02.1930 wirbt Philips im Kleingedruckten für die Röhre 506 für die Lorenz-Empfänger PALADIN 5 und PALADIN 20:

Die Röhrenbestückung des PLADIN 20 nennt allerdings die Röhre 2506, das Schaltbild die RGN1064

506 and 506K tubes

Hello,

Information about the differences between a 506 and a 506K.

I think that there are also two different sizes (height) but I don't know if there is any correlation between the size and the letter K.

It's important for instance in the Philips 2514 model which needs the smaller (height) tube !

I also sent this info to the Tube page (Typical circuit).

Cordially.
Jean-Pierre.

Hello Jean-Pierre

The letter K stands for "kort" in the Dutch language, which means short.

The right hand drawing of a "typical application" for the 506K is not correct!
As you can see on the tube pictures, all of them are directly heated! No additional cathode present.

Kind regards.
