A very special DCC deck :

A beautiful and amazing deck, back in 1979/80 it was highly praised in the French audiophile magazines. It's a great performer with cool features such as, 3 ferrite heads with monitoring, dual capstan transport with two motors, independent L/R calibration for bias and level with built-in test...
