SONY C20 Video Cassette Player (1983)

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 SONY C20 is a mono Videocassette manufactured in 1983

The SL-C20 was a stylish slim looking basic Betamax model. It was the brother to the SL-C30. The difference was that the C20 had no remote control and was silver in colour whereas the SL-C30 was black and had a remote control. Other than this the two were indistinguishable.

These machines incorporated many features of the mechanism used in the earlier SL-C9 albeit stripped down presumably to save on manufacturing cost. Today these machines are beginning to show their age, however, they are well worth maintaining as spare parts are still obtainable.

Other models which were basically the same machine, such as the SL-C40 which featured linear stereo sound were released but in so small numbers it is hard to find one these days. These were also produced in unusual colours such as red and gold.
