valves for sale

Very comprehensive valve data site with a section on tube number systems

405 Line Alive has a technical page: "Decoding Valve, Transistor and CRT Numbers"



BVA = British Valve Association (- a cartel of British valve manufacturers)

For a place to advertise your old valves, I suggest here:
https://www.vintage-radio.net/forum/forumdisplay.php?f=27
Lots of enthusiasts of old stuff.

However, read the stickies.
The site is run very meticulously to the the point of being stifling in my opinion. YMMV.

... and my immediate thought was valves in a car engine. It's sort of on the brain cos I've had to adjust the clearances on mine very recently!

Valves that have broken pins are unlikely to be wanted by anyone, especially considering shipping costs.

Also valves that are really old may no longer be very good.
Over the years they can lose some of the vacuum in them, degrading the quality.

And used tubes are definately "iffy", especially if you can't test them for performance.

European = North America (According to me 1964 GE Manual.
