I bought a used amp with a couple of tubes marked, "12AX7 Schober Organ made in the USA by Raytheon" They appear to be from early '60's. Thanks for any comments.
I never cared for sound the Raytheon 12ax7, maybe I never got a good one. That doesn't mean you won't like them. The only way you'll know for sure is try them in your equipment. Sorry if this doesn't help.
