Sold my tube preamp recently and will be selling off my back-up tube stash.
Ran these four tubes for a
very short time. 20 hours tops. The Amperex 7308 was better in my system.
Getting very hard to find these days. Upscale even ran out.
Would like to sell these off as a quad set or two pairs. Price includes shipping.
Quad = $700
Pair = $400
