1958 Model 3
back to gallery

Although first made in 1958, this model was not released in Britain until 1962.

It was a three speed, half-track mono machine.

According to Swedish tape recorder afficianado, Ricard Wanderlöf, the Model 3 contained two audio amplifiers, the second being for the playback of stereo tapes even though it could record in mono only.

The Model 3B did not have this facility and was a mono two-track record and playback machine.

The quality of sound reproduction of the Model 3B was said to compare favourably to the four-track series 6 although this machine was, due to its age, quite a bit less expensive.

Two half-track heads were fitted with a single motor providing all tape movement.

An EM 71 magic eye valve indicated recording level and the traditional Tandberg joystick control selected all transport functions.

Other features included a clock-type counter, two recording inputs capable of being recorded at the same time, pause or stop button (later models), and monitoring by headphones or external amplifier. Tapes fitted with metal 'stop' foils automatically stopped the machine (motor only) at the end of the tape.

Additional images, circuit diagram and user manual for this recorder are featured on the CD-ROM.
