Today thew mail brought me a couple of valves/tubes.
Unfortunatlely there's nothing left of the markings!
- So, now im trying to ask the experts at RAT:
" Does any of You know what tube it is? "
- I think it could be a Philips. This based on the form of the glass, It
looks quite like a F443N

I have posted a couple of pics at "dk.binaer" under "tube/rör"

Can any of you help me raise the glow?

Best regards

Gee, this photo is rather like looking up a lady's skirt.

But no grid up there!

Tonni,

these appear to be Mullard FW4/500. They're Philips' AZ50 equivalent but
MUCH better sounding.
