Selling my matched quad of the highly recommended Black Treasure 6CA7-Zs (EL34 equivalents).  Wonderful in the 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.  Note that these are a $500 option through Decware...

I also 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 $250, obo.  Buyer pays all shipping and paypal fees.  No DOA Guarantee.
