78S05 2A Voltage Regulator Replacement for Sinclair ZX Spectrum 128 & +2

Power stability is the backbone of any successful retro restoration. The 78S05 voltage regulator is specifically suited for the 128K Sinclair models, which require more current than their 48K predecessors.

Why Upgrade to a New 78S05?

Higher Current Ceiling: Rated at 2A, this regulator handles the load of the 128K “Toastrack” and the Grey +2 with ease, reducing the strain on the component compared to standard 1A versions.
Thermal Efficiency: Modern manufacturing allows for better thermal performance, helping to keep your Spectrum’s internal temperatures under control.
Direct Fit: This is a standard TO-220 package, making it a “drop-in” replacement for the original part on your heat sink.
Tested Reliability: Brand-new, high-quality components from reputable manufacturers ensure your machine is protected against voltage spikes.

Compatibility:

While this is the standard for the ZX Spectrum 128 (Toastrack) and Spectrum +2 (Grey), it can also be used as a heavy-duty upgrade for the ZX Spectrum 16K/48K and Spectrum Plus, providing even greater reliability for machines with multiple expansions.
