Just picked up a Dynacord DS-10 preamplifier made by the Pentron Company in Chicago, IL in the 1950's. It's an all tube design with a single output, and a Radio (line-level?) and Microphone input both 1/4" inputs. I got it next to nothing and I've been wanting a tube preamp for random applications around the studio. My roommate fixes Fender tube-amps and I've got a couple years of building and fixing circuits, so I figured we could figure it out.
I wanted to ask the community though: Does anyone know anything about Dynacord? What about the preamps?
Apparently the unit passes signal only "part of the time" with a light noise. With it's age I'd imagine it only needs a cap job, new tubes, and a really good cleaning. The tubes in the preamp are as listed:
6BQ7 (x2)
6BQ7A
12AY7
12AU7
5Y3
If anyone has advice or information, advice on replacement tubes/parts, or opinions would love to hear about it.
Best,
Ryan
