Description

Selling a pair (two) of RCA 6GU7 vacuum tube(s), preamp tubes. I have a third I will throw in for free. Sold to me testing "good" and I used less than 10 hours each in my integrated amp. Sound great. No noise or microphonics. Comparable in sound to 6CG7 or 6SN7, but maybe a little brighter. I used in an amp designed around 6SN7. You should check to make sure they would work in your amp if you intend to use as a drop in replacement. Whether using as a drop in replacement or designing a kit amp, the 6GU7s are much cheaper than those other tubes. Come in original boxes, but note boxes are deteriorating, taped. I am an enthusiast, not a dealer. I welcome questions and discussion. These are used vintage electronic components sold as-is.
