Decision on pre-amp tubes

Post by MeathooK »

GE 50's 12ax7's or RCA Blackplate 12ax7's, I want some opinions before I let Sarge know what to send me! Thanks in advance.

Both are excellent. The blackplates are legendary. What amp are they going in? I find later (60's and 70"s) GE's too bright for Marshall-type amps to my ears.
I like the GE's a little more in BF/SF Fender amps. Blackplates are great in everything else. I mix and match tubes in different stages....so maybe get a little of both flavors?
Of course...like anything else, this is just an opinion.

They're going in a Carvin amp, but eventually in an 18w when I get the funds to afford the kits! The amp is a high gain amp, looking for classic rock tone, it's a 100w 2x12 combo.

If it's high gain like JCM _00 or a SLO....make sure you get whatever has low microphonics and noise....7025 maybe....but then again, the 7025 is really bright in some circuits.

Buy both brands, you can't have too many 12AX7s!

Having said that I run RCA black plates in everything. They're just that little bit furrier and crunchier in high gain amps and that little bit warmer and more articulate in Fenders.

I have a ton of the GEs from all eras, they're good, too. Stick the RCAs in the first preamp stage and GEs everywhere else, that works fine as well.

I'll second what Novermberrain said; I just bought 5 RCA blackplates yesterday and tried them in my JTM45 I immediately fell in love! Maaan these sound nice!

I haven't tried them in my 18W yet but I'm sure I won’t be deceived.

Cheers.
