Pros and cons of vintage Dynaco ST-70


I like the way old Dynacos look. But don’t know anything about the way they sound or perform in general. For instance, are there any reliability issues with them. What would be a good vintage preamplifier to pair with a Dynaco?

Many thanks for your input.

Frank Van Alstine had (and has?) an extensive ST70 mod which greatly improved it, as did Bill Johnson in the early days of Audio Research. Frank also modded the Dynaco PAS 2/3 pre, which was a fitting companion.
