Update- I hooked up the Maggies last night and played the system for about 3 hours. It sounded great. The cold, hard, brightness was gone and the soundstage was deep and wide. The system was turned off last night. When I came home from work today, I turned the system on. As soon as the preamp's mute circuit turned off, I heard less than one second of music followed by a snap and the amplifier going into protection mode. This was with the 7308 tubes back in the pre. I put the EH 6922s back in and guess what- no cracking, no amp shutting down. Everything seems fine. To recap, I have never experienced the problem with the EH 6922 tubes, just with the 7308s.
I guess it's time to retension the tube sockets as I have no other idea what to do. It seems strange. If the sockets are the problem, why doesn't it occur with the EH 6922s in the pre? Perhaps it's a slight variation in pin position between the tubes. Totally guessing here.
If anyone has any other ideas I would obviously love to hear them.
