I got a pair of Takatsuki 300B tubes. Still have 1 year warranty from partsconnexion. Purchased in mid November so less than 1 month old.
Total use less than 10 hours. Basically new. I will include 2-day air shipping to continental US at my asking price. Thanks.
I will consider trade for a new condition
