Description
The TC 250 was a quarter-track
stereo tape deck, very similar to the TC 350
but with just two heads instead of 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.
Additional images of this recorder are supplied on the Get Reel Vintage
CD-ROM.
