Excellent Vintage 6189 / 12AU7 Preamp Tubes - Sylvania

LIMITED SUPPLY!!These are great Vintage (testing excellent) 12AU7 preamp tubes, selling individually. These bring down the gain to about 20% from a standard 12AX7/7025 style tube, and with good tone for amplified harp. I also have standard 12AU7 tubes and other industrial variations available, including 6189, 5814, and 5963...all are 12AU7 tubes, some being industrial/military grade.

From years of collecting and using vintage amps, I have a supply of tubes handy here always, but I am letting a small number of them go now, especially when some tubes are getting harder to find for some players. In vintage as well as newer amps, good vintage tubes definitely make a difference, especially for harp!
