Ok, now that I have changed out the speakers, output tranny, filter caps and many other parts, it is time to start fine tuning this thing (It does sound a hell of a lot better already). I thought I'd start looking at tubes and tube prices. I currently have the Valve arts KT66's, a chinese GZ34 and I have the stock preamp tubes. I'm guessing the preamp is a good place to start. Any recommendations for preamp tubes without going completely broke? Any advice on power tubes is equally welcome.
