I have a couple of 1943 Amperex JAN-CEP-120 tubes, NOS in boxes.
It looks like a smaller version of a 211(vt-4c) or 845, the only reference I can find about them is a pair for sale on a chinese website last year.
Does anyone know what they are and/or have any specs?
The picture attatched shows an amperex 211, the cep-120 in the middle and an 845 on the right for scale.
If suitable, they would make a cute SE amp, but replacements could be scarce.
Regards,
Dave.

An externally hosted image should be here but it was not working when we last tested it.

Lemme guess :
RNZAF Weedons -> Ferrymead museum -> Lyttelton tube chap -> You
Anyway, got plenty of spares if you do build something

I hope you don't mind me using your topic 🙂
Can anyone identify tube in photo ? It is a noval (9-pin) tube, about the same height as EL84, there appear to be few pins unconnected which would indicate a double (FM detector ?) diode. The print has been completely wiped off and the etching doesn't look like anything familiar either. I believe it came from an old radio, although I can't be 100% sure of that. I've never seen a double diode arrangement with anodes perpendicular to one another, sharing same heating element in the center 😕
(photo is 335 KB in size, not dialup friendly)

Wow guys, it never occured to me that those small anodes could take that much current so my assumption was some oddball detector diode, but based on your replies I went searching for photos and came across this one which looks precisely like what I've got here.
This is the kind of EZ81 I was used to seeing, it looks completely different.

Close enough 🙂
Any thoughts so far in their suitability, or has anyone ever heard them working in an Audio amp?
