I'm hoping someone here might be able to help me. I've been using the Mastersound Reference 845 SET Amp, you see shown above -{the top pic is of my actual amp}- for the past 20+ years and in the past month or so the sound has become extremely strident and bright sounding. Is this the typical sound of a tube amp that needs to be recapped? Or is it indicative of another problem? I know something is definitely wrong and to replace it with Mastersound's present Evolution 845 would cost $18K, which I cannot afford! What do you guys think I should do?
