Description
Affordable price and a wealth of features
The WM-55 was well made and finely finished, the cassette door even included a small catch operated by a slide switch to prevent it falling open, another unusual feature. The mechanism, which used a metal chassis and included switchable auto reverse (sides 1 and 2/continuous play), was shared with models such as the WM-75. Also in common with the WM-75 were Dolby B noise reduction and normal/chrome/metal tape compatibility.
It was unusual for two reasons:
1) It was available in vivid pink, an unusual colour for a Sony Walkman of the 1980s.
2) The radio unit was in the shape of a cassette, model CTP-1A.
Other manufacturers like Sanyo and Toshiba, frequently offered radio modules of this type. Sony usually miniaturised the radio circuit so it could fit somewhere inside the normal Walkman case, such as inside the cassette door (e.g. WM-F10, WM-F107).
CTP-1A radio unit
It enabled the reception on both the AM and FM (mono and stereo) bands. The tuning and waveband controls were accessible through a slot in the side of the WM-55 main unit. The tuning scale was visible through the tape viewing window and the unit was activated by pressing the play button. The interconnections that were made as well as passing power and signals also stopped the motor running, conserving battery power.Via Walkman Central (edited)
