Not the conversation you wanted, but you might just focus on member bwhite's posts in the 'preamp deal of the century' thread. If I recall correctly bwhite was one of the eariler tube rollers and power cord rollers for the supratek preamps. I bet he's covered this topic in detail. And with regards to that thread, I can imagine any Supratek owner not printing out that thread and at least skimming through it (if not reading it completely!). Sure there is a wealth of knownledge about the supratek to be gained from there. You should be so fortunate.
