Hey guys, over the last 14 years, I’ve ended up with a bunch of tubes. Almost all of them I know but no idea about the ones here. If anyone has insight if they’re worth anything or what type of tube it is, I’d greatly appreciate it.

CV4034 is a 12AU7 (ECC82) made in the Brimar Rochester factory. Similar to the Brimar CV4003. An excellent and highly regarded ECC82/12AU7.

6H23P-EB is the Soviet era equivalent to a 6922. From 1983 manufacture. The ones made in the 80s aren't considered nearly as desirable as 60-70s production.

Hope this helps!
