Dynaco has been dead longer than Ronnie Reagan's penis and nothing
stops ST70 repair and refurbishment today. And people misguidedly
recreate Western Electric amps fifty years after they were considered
well and truly useless. But they work like thay always did.

Yes, if kept inside, clean, and not abused most will run forever with
only electrolytic cap replacement. In PA service they lasted a few
years which was enough. They are a challenge to fix even for the best
solid state amp techs today-fixturing and curvetracing parts is a
necessity along with bipolar current limiting supplies for
divide-and-conquer sessions.
