Will Vincent "Dynaco" Amps

I have one of Will's Dynaco ST-70 rebuilds. I have found it to be a very good amp. It has a nice smooth sound. It also very good bass for a lower powered tube amp. Though the sound was good the way it came, i couldn't help but roll some tubes. I ended up with winged "C" el-34's, RCA 7199's and a Mullard gz-34. With these tubes i feel the amp jumps up another level or two. The tube that made the biggest difference was the gz-34. They aren't cheap, but the improvement it made to the overall sound is well worth it.

Dav65mus,
I was not aware i could use kt66 tubes in this amp. I know i can use kt77's. I will have to look into this. By the way the amp is a work of art. My girlfriend thought it was a bomb when i openend the box, but i think it looked great.
