Description
The TC-250 was a quarter-track stereo tape deck, very similar to the TC-350 but with two heads instead of the TC-350’s three. As was the case with the TC-350, all the recording controls were hidden under a sliding panel directly beneath the two VU meters.
The deck could be operated in either vertical or horizontal position. An all-idler, beltless tape drive mechanism produced wow and flutter figures of less than 0.19% at 7½ ips and less than 0.25% at 3¾ ips. Other features included auto-shutoff, 7″ reel capacity, headphone jack, twin VU meters, pause control and an integrated (DIN) record/playback connector.
