For Sale are a quad of the Black Treasure 6CA7 power tubes. These tubes were purchased as back ups for my Yaqin amp that has been sold to a fellow club polk member
The state of these tubes are as follows:
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.
Tested them on a 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 $185 shipped
