NOS RFT 12AX7-ECC83

East German 12AX7. Less bright and earlier breakup than other 12AX7s.

VERY nice guitar amp tube in this price range. These break up earlier and are a bit darker souding than other 12AX7s. Perfect for Marshalls, Voxes and clones of these amps. Sound nice in Fenders and Fender clones too. Limited supply on hand. Various tube markings including United, Pinnacle, RWN, Tesla, etc.

These are so much better than the stock tubes in my Diesel "Herbert" amp, I can't believe the difference!These things smoke! I'd like one more please. Dave Gerlach

Hi Mike...I retubed my Carmen Ghia head preamp section today with what you recommended.  I just wanted to say it sounds amazing...betyter than I would have hoped for.  I know NOS RCA'S are great, but I believe the RFT made the biggest difference.  A great tube and a great choice.  Thanks for the help.

Mike:

The RFT 12AX7 removes the harshness that I was experiencing from the amp (Dr Z Maz Jr). Just as I had hoped. Even more impressive is the fantastic breakup / drive of this tube. What a fantastic tube for a blusy drive sound, and it still produces a fantastic clean sound when not overdriven. It really suits me that it is a bit darker overall than the Tung-Sol I had in V1. I doubt there is a better tube in this pricerange.
This tube was an excellent recommendation.
Thanks,
Eirik
Mike: I'm sure you hear this a lot but these RFT's are just the best in my old Boogie (MKIII Simulclass head). Never sounded better!

Hi Mike,
I just tried out the RFT 12AX7 you sent in my Presonus tube preamp and it sounds great! Very smooth overdrive, nice detail, and quiet...
Thanks again for another good tip!
Best,
Greg Passler
Mike:

Actually, the RFT sounds friggin great! in V2 of my Two Rock Em Pro. Very textured, for lack of a better term.

Thanks again for the great tubes and the lightning fast reply

Mike:

I put two of these in my Matchless Spitfire and they made a HUGE difference. They warmed up the amp and make it break up sooner...exactly what I was looking for.

Thanks,

Bill Hayden
