OverviewThe 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 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.
