Soundcraftsmen heyday was the mid 70's to mid 80's. They specialized in equalizers which were all the rage back then.
I owned the PE2217R pre-amp/equalizer which was in J.Gordon Holt's Stereophile list of recommended components. I had the piece for four years. It sounded good for its day and it gave me no trouble.
Soundcraftsmen also made a line of power amps. I think what you have is from the early to mid 80's. Around then they broadened their line to include a tuner and a cd player. That stuff was made in Japan. The power amps, pre-amps, and equalisers were made in the USA and were proudly advertised as American made.
