12EM7 can you find an electrical sheet?

Tubes Asylum

Questions about tubes and gear that glows. FAQ

The 12/10/6EM7, I am told, all were used as vertical oscillators in TVs. The small triode has excellent gain and noise characteristics and is good for input gain. The larger triode has plate resistance of only 750 ohms and can be used as a driver - a twofer.

I use the 6EM7. I have them. It's on Duncan. They work great, but for the life of me I can find no information about the 12EM7, anywhere, except one mfr's page (McAlister Audio). He referred me to the RCA receiving manual, but I could find no 12EM7 at all.

Can anyone help?

I was led astray by the "12". It didn't click until I looked carefully at Duncan - Frihed89 01:22:28 04/25/10 (1)

You can't find 12EM7s because they're 13EM7s. - jeffreybehr 10:07:06 04/24/10 (1)

I was just beginning to figure that out in Duncan - Frihed89 13:40:23 04/24/10 (0)
