Scored a quad of Telefunken brown base OO getter EL34s and a few vintage 12AX7s.
Can anyone confirm the brand of this 12AX7? It looks like an RCA to me...
Also, what would the Telefunken tubes go for these days? I'll try to test 'em in the near future, but it came from an amp that is in pristine condition (from 1972), so I assume the tubes don't have lots of hours on them.

Does the preamp tube have markings on it confirming it’s a 12AX7? I ask because I’ve seen the 12AX7 and 12AU7 look almost identical.

No. I've started to wonder if these are the more common clear-top 12AU7 tubes from RCA. I'll swap in some 12AX7s to see if the gain jumps up. But first I must upgrade the power cord....
