mfoley3... As you can see I'm running the GAT/LP140s as well. Quite some time ago, maybe two years, I replied the output tubes in the 140s with KT120s. I've been very satisfied with the change. You don't get more power because the driving voltage/current is not increased, but I believe there's more loud passage head room for the amps. The sound is still wonderful, no negatives and maybe a bit better. Tube longevity should be better as they are operating at less than capacity. The only downside is that your tube cages will no longer fit as the 120s are a bit taller. I don't use the rattle things anyway. But the amps look way better with the larger tubes so for me a plus. Go for it... it's plug n' play. Put them in, bias and go.
Enjoy, Bob
BTW... Lew Johnson is a friend and recommended the 120s. At the time he referred to them as the new super tube and even thought they sounded better.
