Made in 1978

250 watts per channel (or is it mono?)

Soundcraftsman is a grunty amp made for crankin'. Sometimes you still see them in use at rehearsal studios or in old clubs. I never heard a 5001, but I remember S.C. as a very hard hitting amp for the power rating, and not bad sounding really. Bi-polar direct coupled I think. Creative Acoustics in Raleigh, NC used to sell Soundcraftsman. (they might tell you about it too, if you can't find any more info online)
