If you want an expert to upgrade your amp, try the Dynaco Doctor at
http://www.curcioaudio.com/dynadr_3.htm. He just upgraded an ST-35 amp for
me, and it sounds great. Both power supply and passive parts were upgraded.
Joe Curcio knows what he's doing.

I recently purchased one of these little amps and was wondering what I
should do in terms of mods if any. I am not at all familiar with tubes so
I
really can't say if I am getting good sound right now or not. Any help
would
be greatly appreciated.
