Each
RFT is a German brand. The RFT ECC83 / 12AX7 is a durable tube with very low microphonics. The RFT ECC83 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 RFT ECC83 tubes in our own white boxes.

Logos may vary from tube pictured, but construction is the same.

Spectacular tube

by

After reading so many positive reviews I bought 2. One for my Peavey 5150 with SED Winged C 6L6GC's & one for my JSX with SED Winged C EL34's. Both in V1 & made all the difference in the world. Such a well balanced tube & three-dimensional. I've only been able to set my guitars down long enough to order more since they've been installed. I never thought a preamp tube could make such a difference. 5 stars all the way around!!!!!!

Made a great improvement....

I bought 3 of these for a Marshall 1959 Plexi Reissue.I had 3 Tung-Sol 12AX7's in V1,V2,V3. Decided to try out these RFT's and see if I liked them.Replaced only the V1 position first and it made a GREAT difference.(Left the Tung-Sol 12AX7's in the V2,V3 position.) Didn't think changing one tube would make such an improvement. Wish I found out about these earlier.

Great tube

by

My Rivera amps love these. It's like they were what the designers had in mind when building the amp. Fat, rich, and creamy without losing clarity. Not a dark tube but more a warm tube. If you have an amp you like to push the power section on, put one of these in your phase inverter spot! Been tube-rolling for 30 years and these are some of the best I've used!

Great in Marshall DSL40

by

Dropped this bad boy in V1 in a Marshall DSL40 and I must say it has superb tone. Highs are nice and round and excellent lows and mids. Even sounds phenomenal in V2 (high gain stage). A great deal for a NOS tube.

Sweet Tube

I can't get over how quiet this tube made my JTM 45 head sound. The tone seems to come out like never before, with articulation and sensitivity coming of the guitar i never knew was there. Its a great find and a great tube!!
