Pioneer RT-707

3-motor 4-head reel to reel tape recorder (1977-1981). The Pioneer RT-707 has a tough and reliable construction. The unit combines a 5mm thick front panel and a die-cast frame for the outer casing to protect the heavy inside parts. The construction is designed to display the maximum precision and durability, and the front panel can be mounted in a rack conforming to EIA standards.

Price: € 1100
