I have several Matched Pair and Single Tubes listed. They are described below. All have been tested on a tube tester and checked by listening to in either a preamp or amplifier to be sure they not only measure well, but also sound good. Test as new. I have had these stored and am thinning the herd. I have more tubes than I will ever use. Tubes will be well packed for safe transit. Buyer pays shipping. I usually ship on Tuesday and Friday. Take a look and see if there's something you may like. Please note- I had many more tubes listed and they have been sold. USAM doesn't allow me to remove any of the pictures, so the corresponding photos are noted in the tube description.
