      Tracopower-TSR 1-2450-Converter 5V. Reduce your Sinclair ZX81 case temperature.

      This appears to be a brilliant replacement for the 5V regulator used in the Sinclair ZX81. It just fits in nicely, runs very cool and means there is no need for the heat sink thus reducing the temperature within the case by a large amount.

      Traco Power Review

      Great product that is an efficient power regulator that operates in a wide temperature window without the need for an additional heat-sink.
