Studiomaster Studio 4 Professional Mixer 4 Track Cassette Recorder - Rare.

Apparently one of the best in 4 track multitrack recorders - professional quality, made in the mid 80s and built like a tank. I have never been able to find a manual for this so haven't been able to test it properly but bought as working and never used. I think needs a professional to service it. Has some caps missing from the pots.

Collection preferred.
