Anyone have curves for a 2C52?

bst · 22nd January 2010, 07:48 PM

I discovered several of these while trying to organize the horror show in my basement. They appear to be a sort of supercharged 12SL7 - Raytheon data sheets show a Mu of 90, and one web reference states a mu of 100.

Anyone have plate curves for these, or experience using them as an input tube?

Thanks.

it seems to be a 12AX7 in octal socket, or more precisely high mu dual triode in pre-9pin era. I am also interested to know if anybody has experience on them
