Modern version of a Dynaco ST-70
« on: 26 Mar 2010, 03:40 am »
Here is what came up with for bringing this classic amp into the modern age. I changed the layout and used Shannon Park's driver board. The only original parts are the output transformers. Everything else is new, including a custom chassis and cabinet I built. I'll get some better pics in the day light. I took these a few minutes ago.

Lovely, just lovely. I remember looking at his board, it uses a CCS if I remember correctly.

Beautiful amp.  :bowdown:
