The official power supply for the Grey version of the Sinclair ZX Spectrum +2, from the Amstrad era of the Spectrum – the +2A and +2B.
It is the one shown in the photos below (see the bottom for all photos).
Tested and working, with electrical safety checks, new UK plug and packaged to protect.
This is for the Grey +2, but it is also the most versatile Spectrum PSU. It is also suitable for the earlier versions of the Spectrum 128 Toastrack, Spectrum Plus, or both 16k and 48k rubber key Spectrums.
It is not suitable for the Black +2A/+2B models or the +3 model (disk drive model), as described in the series of articles by PopeyMon on this website.
