Vintage GEC Genelex Gold Lion KT-88 matched quad .
Original purchase from Andy Bowman of Vintage Tube Services , used a few hours and stored for last 20 years. The labels have rubbed off of 2 tubes . They all test as new on calibrated
hickok 533a and in my Push Pull Triode amplifier. Gm is matched within 10% across all four tubes.
Current in my amp measured between 59.5ma to 61ma
gm results 7000, 7000, 7500, 7750, 7750 where average new is 7000
all test ok for gas,shorts and sounded glorious with good emission.tubes will be well packed, tubes are being sold as-is, no returns, buyers pay actual shipping and paypal fees.
USA sale only, don't believe the hype ! The new production russian reissue can't hold a candle to sound of original Genalex kt-88 tubes
