12AX7 Raytheons

I agree completely with Onhwy61, with emphasis on "but whether or not you like or care for its sound in a specific application is a whole other question". I love the sound of my 60's vintage Raytheons in my EAR phono stage. They have a clarity and purity throughout the frequency spectrum that is great, and that is lacking in even my overall faves the Telefunken smooth plates. Granted, the sound of my set-up is very full and not thin at all, so the Raytheons' sound is welcomed there. If you get the chance, checkout the Raytheon 7025's; similar with a little more meat on the bones.

here are some others:
Siemens/Halske NOS
Mullard Nos
RCA Clear Top NOSs

less exspensive (not in league with above,but very nice):
Create 12zx7 China
Tube Stores Prefered 7075

in a previous conversation we had, these were 213Cobra's recommendations. He know his tubes.

Not me, Amperex Holland are one of my fave 12ax7's as well.
In general I just punt with RCA blackplate.

No experience with the Raythons, my NOS Amperex 12ax7s/Holland 1960s does it for me, but having no referent makes it impossible to (truly) know how good they are. I was told, from an expert tuber, these are sure winners. Anyone want to bust my bubble, feel free.

Raytheon made a fine 12ax7, but whether or not you like or care for its sound in a specific application is a whole other question. In general, tubes made for organ applications have been selected for lower microphonics.

I never liked their sound either, were so/so at best in my PAs3 and minimax pre-amps.

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.
