Help me to identify unknown tube

Milen · 25th January 2008, 04:22 PM

As you can see on the tube base is written "036" and "A.25.52" "F8.0". The anodes are big and flat... The base is like on AZ1, but I cant't find similar AZ1 to this...

Looks somewhat like a dual diode.

Yes, it is dual diode...

Looks like German socket.
AZ36?

I never heard of such tube. May be AZ11?

Edit:
Here is some interesting document:

I am almost sure it is an AZ4. This one has a P-socket and has abot the same ratings as a RGN2004.

Hoping this may help.

AZ4

Looks a LOT like the AZ4 I have here...

to be even more specific: I think it is a Tungsram AZ4. The plates are placed really close together, almost in the center of the glass-bulb. I only have seen Tungsram tubes having this structure..
