Tandberg TCD-300

1 9 7 2 1972
1 9 7 4 1974

Original version of the the-Tandberg-cassette-recorder which would see many versions : TCD-310 (1974), TCD-310 MkII, TCD-320, TCD-330, TCD-340A, TCD-440A, TCD-420A, with goodies throughout such as soft-touch transport controls, azimuth & bias correction, 3-heads and Type IV tape as early as 1978 !

The last version, TCD-420A, brings us to 1982, which is when Tandberg made its best but had no more room to develop and sell, cornered by the japanese as everybody else was.

The TCD-300 is based on a 3-motor closed-loop dual capstan drive with two Ferrite heads, a Dolby noise-reduction and even a "special" selector for CrO2 / Type II tape.

Motors are two AC for the reels and one hysteresis synchronous for the capstan - see the TCD 310 follower for images of it.

The TCD-300 can be used vertically, its vertical cassette lid opens to the right and the enclosure is all profiled aluminium with sideburns available in teak, oak or rosewood.

The high-end status of the TCD-300 had somewhat vanished by the late 1970s and was fully gone with the TCD3004 monster in the early 1980s.
But in 1972 this was the top : it offered a joie de vivre, as the catalog said.
