Genuine Sinclair ZX Spectrum U.K Power (Adaptor) Supply Tested And Working

About this deal

A genuine original power supply for the iconic Sinclair ZX Spectrum home computer, first released in 1982. The standard supply delivers 9 volts DC at up to 1 ampere, and the original design uses a centre-negative polarity, with the outer ring positive and the inner pin negative. Original units are unregulated, meaning the actual output voltage can vary depending on load, which is perfectly normal behaviour for this type of supply. A genuine used original like this is a practical and period-correct choice for collectors and retro enthusiasts looking to get their Spectrum up and running. Before use, original supplies should be checked for safety as well as functionality, and to confirm they are delivering the right voltage, current and polarity -- which this item has been tested and confirmed working. Connecting an incorrect polarity supply to the ZX Spectrum can cause significant damage to internal components and any peripherals attached, so a verified original is a reassuring buy.
