Technics RS-M10 Cassette Player (1979)

As the world moves ever forward and new technological breakthroughs enable us to experience our music and video on ever smaller and better devices, I want to pause and take a look back at some old equipment that I have here, mostly lying in cupboards, wardrobes, in the attic and even under the bed. The items on display are from my own collection however I am on the lookout for our listeners to send in their own images too for display here.


This Technics RS-M10 is a stereo cassette deck with Dolby B noise reduction, it was first sold by Technics in 1979.

The main features of the Technics RS-M10 are 2 heads, mechanical 3-digit tape counter, manual tape type selection and capable of handling normal, chrome and ferro-chrome tapes, belt driven single-capstan transport.

Typical front-loading cassette deck with the cassette compartment located on the left side of the deck. Tape eject is operated mechanically and the cassette needs to be placed with the side to be played facing forward in the cassette well.
