Fantastic, sounds like a theme for another topic but I am a great fan of the KT66 and have a number of vintage amps that use them from Pye, Pamphonic, Sound Sales, Leak (TL12’s) ,HMV Williamsons and others. I am lucky to have many spare MOV valves, will certainly see me out. But my perspective is very much that of a collector, I can service or repair vintage amplifiers and televisions, but my knowledge of electronics is pretty basic. I also have several thousand LP records, mostly 60’s and ‘70’s Rock, Prog, Folk etc but I have to admit some Pop too. But mostly renovating my ancient farmhouse and barns for the last six years though.
