I took all 4 of these KT66 from my amp and replaced them with 6L6s, which are stock for the amp. They sound great the tubes are in good physical condition. I tested all of the tubes on a vintage Mercury Tube tester and all 4 test well within the ”Good” range (all were between 74 and 80 out of 100).


A brand new matched quad costs $280, but I’m selling these for $120


I’m not a professional tube dealer or tester, so I can’t guarantee they won’t have any noise or rattle. They sounded great when they were in my amp and just tested well within the “Good” range, so to the best of my knowledge they will work just fine, but I can’t make any guarantees about the finest details of their sound or performance
