These were included with two other sets of 300B tubes when I bought my Woo Audio WA5-LE, and I simply preferred the sound signature of a different set, but definitely a case of personal preference rather than a clear better / worse. They were actually the quietest tube (noise floor) of the bunch, and had the best bass.
They have ~250 hours on them - about 200 hours by the original owner, and I added another 50 or so.
They come in original packaging and will be shipped USPS Priority mail. I will cover shipping to the US as well as PayPal fees. International is fine, but buyer pays shipping in that case.
I’m giving a 48-hour head start for this (my favorite) forum until they get posted elsewhere. Happy to answer questions!
