Bear, I have read that the Psvane power tubes can take 300 hours to fully settle in. I don't think these amps are hard on power tubes so they should last a long time. Maybe you can finish burning them in with your new speakers as they settle in? IMHO, rolling tubes will be rather pointless until the speakers get a work out.
I just received a Treasure CV181 and it is supposed to take a good while too.
I've used the Psvane 12**7 tubes and they take a while too. 75-100 hours.
Do you have the British KT66's? I have not heard them or the reissues but I like 6L6's. I have Sylvania 6L6GAY's and I'm trying to decide between the GL KT66's, Valve Art KT66's, Tung Sol big bottle 6l6 or Treasure KT-66's
