Technics RS-M230 (1981)

The Technics RS-M230 is a stereo cassette deck from 1981, introduced in Japan at ¥49,800. It's a compact two-motor deck - 430mm wide, 5.1kg - but the transport is a bit more sophisticated than the price suggests. It uses computer logic circuits that allow direct switching from fast-forward or rewind straight into play, with protection against accidental operation.

An electronically controlled DC motor drives the capstan, and a separate DC motor drives the reels. The head complement is an MX record/play head with double-gap ferrite erase heads. The front panel has a large twin level meter with backlight. A three-position automatic tape selector reads the detection holes on the back of the cassette shell, sets the correct tape position, and shows the selection with an indicator.

Recording features are generous for the class: Dolby NR with an MPX filter out switch, Rec Mute, Auto Stop, Rec Pause, computer-controlled timer play/rec, and a soft eject mechanism. There's also a high-gain headphone amplifier with a double coaxial volume control.

Rated performance is 20Hz to 18kHz frequency response on both XAII and metal tape, 57dB signal-to-noise on XAII at peak level, and 0.04% WRMS wow/flutter. Dolby adds a further 10dB improvement at 5kHz and above. Power consumption is around 15W at 100V AC, which fits a deck aimed primarily at the domestic Japanese market.

Beyond the spec sheet, the record is thin. There's no documented reviewer reception or common-problems information to draw on. A used example from Germany did surface on the Ukrainian classifieds site OLX in 2026, asking 6,999 грн. That at least confirms the model reached European hands, and it's about all the secondary history there is.
