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.

When new, they were reliable and good sounding.

Dynaco also made a pre-amp & tuner...

Think of it this way, they were designed when speakers had much more limited frequency response and digital music didn't exist.  I've played with a lot of vintage Dynaco gear and am not thrilled.  They need modded.

When I was playing around and modding Quad II, Radfords, Croft, Leak, TVA, EICo tube amps, the Dynaco was always considered low rent.
