Traco Power TSR 2-2450 – The Ultimate 2A Cool-Running Upgrade for Sinclair 128K
Heat is the primary enemy of vintage electronics. The original linear regulators found in the Sinclair 128K range are notorious for getting incredibly hot, necessitating large metal heatsinks. The Traco TSR 2-2450 solves this problem by using modern switching technology.
Why the 2A Version?
While many shops sell the 1A version of the Traco regulator, the 128K Spectrum models (especially when used with modern peripherals like the DivMMC) can push close to that limit. This 2A (2000mA) version provides a massive safety margin, ensuring your machine has all the current it needs without the regulator breaking a sweat.
Key Benefits:
- Eliminate the Heatsink: Because it generates almost zero heat, you can often remove the heavy internal heatsink bar, improving airflow and reducing the weight of your machine.
- Protect Your ULA: Lower internal case temperatures directly correlate to a longer life for your Spectrum’s custom chips.
- High Efficiency: Over 90% efficiency means less strain on your external power brick.
- Drop-in Replacement: Designed with a TO-220 footprint, it fits directly into the holes left by the original 7805 or 78S05 regulator.
Compatibility: This module is ideal for the Sinclair ZX Spectrum 128K (Toastrack) and the Sinclair ZX Spectrum +2 (Grey model). It can also be used as a heavy-duty, ultra-reliable upgrade for the 16K, 48K, and Spectrum Plus.
