Oh yes, I know that tube. The original integrated circuit. The simple Loewe OE333 radio it goes in reminds me of the Atwater Kent model 5 which was another multi-stage very simple reciever. Lowe used their unique "multi-valve" approach up thru the 1930s in their radios. Only Lowe made replacements, surprize!

"One of the reasons for the development of this amazing device was that in Germany, there was a tax on receivers based on the number of valves in the set"

Amazing how having to pay extra taxes motivates people! :D

Looks like they also invented disposable electronics. Once the tube goes, you might as well buy a whole new set, because just replacing the tube is not cost-effective.

The radio cost 3 pounds, the tube 2 pounds. :D

Man, when I saw the thread title, I thought someone had found one of these. :(

I'd love to see one live. Yes, it may have been a ridiculous reaction to an asinine tax law, but the craftsmanship required to do this, is pretty remarkable...

If the encapsulated cap was a wax paper one, I suppose it may still be good, as moisture can't get at it.

One U.S. tube had two triodes with resistor coupling in-between. 6B5 in RC-21
RCA Tube Manual, I just looked it up. Actually direct coupling, with a bias resistor
