This was a pretty sophisticated machine by 1973 standards and was produced at a time when TEAC was just beginning to release their professional range of tape decks under the TASCAM banner.
The A 5500 was a semi-professional stereo tape deck with Dolby noise reduction, three motors (a direct drive capstan and two DC reel motors) and auto-reverse with all transport functions being servo-controlled. Four heads were utilised: erase, record, playback and reverse playback.
Wow and flutter were a very low 0.06% at 7½ ips and 0.09% at 3¾ ips with a 30Hz – 28KHz response at the higher speed. The Dolby system could be calibrated for both channels and a 400Hz calibration tone was supplied via a switch on the rear panel for this purpose.
