Up for sale is a NEW matched pair of Shuguang Black Treasure 300B-Z vacuum tubes. Factory matched, tested by me, and never, ever used.
We don't rely on or trust ANYONE to test/confirm/ship our tubes (most certainly not anyone overseas) but ourselves. You directly deal with us, not a broker, partner, intermediary, go between etc. You've read the accolades, now experience them at a price lower than you've become used to. Check out our stellar feedback on tube sales, and buy with confidence.
$250 price includes PayPal fees. $11 for USPS Priority Mail shipping to the 48 contiguous United States.
