This is a brand new, good quality replacement power supply which is 100% compatible with the Spectrum 16K, 48K, 48K+, 128 and +2 (grey model).
It is a modern, efficient power supply rated at 2.5A, 22.5W.
The original Sinclair 16K & 48K PSU's were rated at 1.4A, and the Spectrum 128 and grey +2 at up to 2.1A, so this 2.5A replacement power supply has plenty of additional "head room" for additional modern day or traditional peripherals.
Comes with our excellent Sinclair ZX Spectrum in-line power switch.
Important:
This power supply is wired with the end plug "centre pin negative", so must not be used with any other device than the Spectrum models listed above.
It is not suitable for use with the Spectrum +2A, +2B or +3 models.
