Jetter,
You are right regarding the popularly of the Dyna ST 70 amplifiers, Yes modification can improve them up to a certain point, agreed. I didn’t have the difficulties with mine as Muzikrav experienced. My only point is that you can proceed "-far" beyond the scope of what the Dynaco has to offer . I believe that Kenny was making this same observation as well.
The Dyna ST 70 is very affordable and allows one to experiment with various upgrade projects and learn but IMO it has limitations compared to other options. I would say it does have a nice midrange but has obvious weaknesses in bass and upper frequencies, and other areas.
You can go further with better quality tube power amplifiers, much further. I would not use this amplifier as an adequate example when comparing the merits of what tubes provide sonically versus solid state amplifiers.
