Selling my matched quad of the highly recommended Black Treasure 6CA7-Zs (EL-34 equivalents). Wonderful in the Decware Torii 3! I currently use a VV32B-based amp, so I have no use for these tubes.
A few hundred hours on them, they are fully burned in, so you won't have to go thru the long process to get them to sound their best.
I personally tested them on my calibrated B&K 747B tube tester. On the "good" tube scale of 65-120, the 4 tubes tested: 107, 110, 111, 115. Tons and tons of life left!
Asking $225, obo. Buyer pays all shipping and paypal fees. No DOA Guarantee.
