KT88 TUBES - MATCHED QUAD SET OF 1970s GEC GENALEX BROWN BASE THREE GETTERS

Description: KT88 TUBES - MATCHED QUAD SET OF 1970s GEC GENALEX BROWN BASE THREE GETTERS  Made at Hammersmith ( as denoted by the Z) in the UK -the best of the best. Date codes 7528 Z(x3) ; 7527 Z(x1) ( one date code has unfortunately rubbed off) As you know these sets very rarely come up as a matched quad for auction I have these tubes as a spare set but I felt someone else should get the benefit of them. When last checked they measured ( by a 3rd party tester) strong at 60/60/60 and 61m/A To add to their quality sound and lifespan they have been deep cryogenically treated (DCT) which for people who know about these things offers a dramatic improvement sound wise. They sound remarkable. As you see there is some label-ware consistent with age. I will ONLY send by courier and it will need to be signed for.  For UK buyers the courier is max £25 uninsured. No returns, I prefer payment by bank transfer. INFO: In 1957 England's MO Valve, Ltd. (Marconi-Osram) produced the KT88 tube and sold them under the Genelex and GEC brand names. This innovatively developed tube immediately became the foundation of amplifier designs worldwide in both hi-fidelity and musical instrumentation amplification industries. It was on a level of its own, displaying flawless power and purity without compromise. When legendary American audio component designer Stu Hegeman declared the KT88 superior to the American 6550 tube, all manufacturers followed suit. Today hindsight confirms the KT88 was the pinnacle of vacuum tube technology. It was used in many golden era greats including the McIntosh MC275, Dynaco MKIII, Marshall Major, and many others, and it continues to serve and the foundation of many modern tube designs
