the orginal gent.. I just received a pair of JJ's from Bob at Eurotubes....he was real nice on the phone and gave me some advice about biasing. I'm anxious to get them installed.. Thanks for all the advice... fwiw - I've heard stories about GT over the years too, so I've stayed away and have dealt with Willie (LValve) in the past and now wanted to try the JJ's so I called Bob. The tech's in my area (formerly Wichita and now KC) seem to like GT for some reason though. It's all most of them carry.
