I bought used in 1984 to a friend. It must date from the late 70/debut80. It's very good stuff, built with materials and quality components. He makes his weight because transformers are very heavy. 2x75W power. 2 tape inputs with a copy in both directions, + 1phono, a tuner, one with. 2 speaker outputs (A and B).
it's been 30 years since he turned (almost) every day. INDESTRUCTIBLE!
If you see a trainer, jump on it's very very good stuff (not like now !!!!).
