This model replaced the WM-F64 and added an interesting new feature to the Walkman range: digital preset tuning. This was a real step forward over the mechanical system offered on the previous model, and was more stable, more versatile and easier to operate. The new system featured an accurate LCD frequency readout and allowed ten stations to be stored from either the AM or the FM bands. The display could also show a clock and an alarm could be set that sounded a built-in buzzer at the chosen time. Text copyright © Walkman Central. Unauthorised reproduction prohibited.
The cassette section retained its features of auto reverse, Dolby B NR and metal tape compatibility. The “mega bass” system was also retained and had two positions of effectiveness. The switch for this was moved from the side of the case to a prominent position on the cassette door. The battery indicator was also amended and was now composed of two LED lamps so that the direction of tape travel was also shown. Text copyright © Walkman Central.

The change from a mechanical to an electronic method of programme storage brought with it its own problems. The memory chip could only retain the radio station settings and clock if the power was applied continuously, which was obviously incompatible with the operations such a replacing batteries or connecting an external power source. To get around these drawbacks, a special “double wet layer” capacitor was fitted inside. This unusual device behaved like a small rechargeable battery which drew power from the main batteries when they were in good condition and was capable of keeping the computer memory intact for about 10 minutes, plenty of time to fit new batteries.

The WM-F65 was available in two versions, those with an “A” prefix (e.g. WM-AF65) had a sensitivity switch (local/DX) and those with a “B” prefix (e.g. WM-BF65) had a mono/stereo switch, both of which affected the FM radio only. Text copyright © Walkman Central. Unauthorised reproduction prohibited.
