The WM-FX193 / WM-FX195 are radio cassette players manufactured by the Sony Corporation in approximately 1999. This was a basic entry level model with a plastic case and some useful functions. It has an AM/FM radio, basic tape functions including fast-forward and rewind, and requires only two batteries to provide up to 25 hours playback time.
Although from the outside it appears as a basic model, this model uses the LB8115 audio IC, which is a single chip Walkman IC with integrated stepper motor driver circuitry. The radio circuitry is around the extremely popular TA2111F single chip tuner IC by Toshiba. Consequently, the radio is very sensitive and works well.
A remarkable feature of this Walkman is that it uses a stepper motor for the tape drive, and consequently the speed is uniform and noticeable straight away.
The new design features for this Walkman are simple and elegant. The tuning dial is inside the cassette lid, and a plastic strip connects the dial needle with the rotary tuning control situated on the side of the player.
Interestingly, the battery compartment lid is hinged which is useful as they are usually the first to be lost.
This player comes with a pair of MDR-026 headphones, which provide a good dynamic range and clear sound. The unit operates on two AA sized batteries that provide up to 25 hours of continuous tape playback, or up to 55 hours of FM radio reception.
On this side, there is a standard sized stereo jack socket for the volume control. There is a switch for selecting stereo or mono reception for FM, and there is a rotary control for tuning into radio stations.
This Walkman has Automatic Volume Limiter System (AVLS), which maintains an even volume level, preventing unintended level increases. It also behaves as an automatic gain control to keep the volume to the same level during different parts of the music and tracks.
Cost / eBay
This model was mass-produced and therefore it is not so rare. A used second-hand working player in average condition can sell for around £5.00 on eBay. A brand new one in the original bubble-wrap packaging can sell for much more depending upon the number of bidders on the day.
