[QUOTE="Agaton Sax, post: 715223, member: 2475"] I think results of tube rolling are vastly over exaggerated, however there are 6922s, then there are European E88CCs and so far ahead you can barely see them are Siemens cca. Most recently in my application they knocked a Valve Audio Whisper into a whole new league. In this country they were mainly used in instrumentation devices by Eskom etc. In these sort of applications they were usually pulled after a certain number of hours,regardless of condition. Result of this practice is that if you know where to look there are some amazing Ccas around [/QUOTE]
