    Guido, I think SPL sells the replacement tube for the Channel One directly to users -- might be your best bet to keep one on hand. Since the Channel One is still in production ($1400 new in the U.S.), if you are able to isolate the problem to the preamp you might want to give SPL support a call for advice before you replace anything. As I understand the Channel One design, the front end of the preamp is solid-state and the tube is on the back end to add "color." So, IF the preamp is really distorting without being over-driven, the problem could be in the solid-state circuits up front (let's hope not!).

    I'm still betting on the mic/mic technique!
