Description
The X-20R was a high-quality quarter-track stereo tape deck with bi-directional record and playback capability. It was fitted with DBX noise reduction circuitry and had a 10½ ” reel capacity.
The transport system utilized three motors and a dual-capstan closed-loop drive. This system acted to isolate the tape from tension produced in the reels, and hence increase stability because the length of unsupported tape was kept to a minimum. The capstan shaft was kept in firm contact with the thrust bearings by an arrangement of two magnets TEAC called “Magnafloat.” As is the case on X series decks, the more expensive ones, like this one, feature electronic breaking.
Internally virtually the same as a X2000R and significantly rarer.
If you own an X series Teac you may want to read the Service Considerations detail on capstan motor issues.
