Genalex New Sensor Corp Gold Lion Matched Quad KT88 Power Tubes. I bought these for my Macintosh 275 which then went into storage after replacing the amp. These have 15 hours on them tops so next to new. Great sounding KT88's. These are the New Sensor Corp. reissue of the famed Genalex Gold Lion KT88. The tubes have gold plated grid wire, carbonized screen grids, and a tri-alloy clad plate structure. The sound quality is truely exceptional.
