506*Branded Audiola type NVD3

At the end of 1920's or early 1930's the Nordisk Solar Co.in Denmark sold Philips tubes under the Audiola brand name. At least I have a tube with a label at the base with the text: Audiola, type HVD3, a/s Nordisk Solar Co. At the top of the glass is printed: Philips, 506, Miniwatt.

506 and 506K tubes

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.

K = short

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.
