Hi Jma@mailhost. I had a similar problem with the VT60Se. Don't know whether new tubes will make any difference, didn't stick with it long enough to collect a drawer full of them tubes! Go audition some very fine SS class A (op. mode) amps available either new or resale, i'm sure you will find one which will work well with the rest of your system. The good aspects of class A type SS amps are worth to seriously consider. Of course there are also esoteric class A tube amps which are in a different league(price) altogether. Nice hunt, Phil.
