RFT ECC83 / 12AX7 Preamp Vacuum Tube
RFT is a German brand. The RFT ECC83 / 12AX7 vacuum tube is a durable tube with very low microphonics. The RFT ECC83 preamp tube is well known as a fantastic hard rock "crunch" tube in Marshalls, Mesa-Boogies, and similar amps. They are slightly darker sounding than many other 12AX7/ECC83 tubes.
Our stock was received in bulk packs so we have packaged these ECC83 tubes in our own white boxes.

Great tube
by Max
The RFT ECC83/12AX7 tube is a bit "under-rated" if you ask me. This tube is dark like a standard JJ, but has an open, full, lovely tone like a good NOS tube would have. This thing is dead quiet for an old tube as well. Cannot go wrong if you have never tried one!
awesome tube!

I find nothing dark about them in my tsl100 nos tubes kill the current production stuff if you want your Marshall to scream these are the bomb!
My Review
by R.N.
I got one.
Oh my god!
I put in V1 of my Vintage Modern, and it completely changed the amp. It's smooth and high gain, with tons of tight low end.
Thanks!
