DYNACORD ECHOCORD SUPER 76 AND EMINET II.
Are an hybrid (tube and diode) effect and audio system, s76 implement a tape delay and a reverb unit, is a clone like of the famous series Roland spache echo series.  the restoriation work of the echo unit was been difficult and tedious  because the internal connection cables were old and broke just by looking at them, I had to replace them all. photo you see where taken before the restoriation process.
