Gaugemaster are at Ford Arundel if you are looking for phone number. **Q: can you use one 16vac to supply both AC inputs on this unit? Is there a supply for accessories ie points and turntable?** A: I have a two track layout so I use one outlet for each run , also I use one 12v outlet for my points and one 12v outlet to a 3 / 5v transformer for all my light etc, hope this may help. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Highly recommended *by D***N on 19 March 2025* Very cheap on Amazon to buy came very well packed very smooth operation with slow running. Perfect piece of kit for any model railway. Ease of use. ### ⭐⭐⭐⭐⭐ Worjs great *by D***N on 8 January 2026* Required a supply unit which would be helpful to know when buying ### ⭐⭐⭐⭐⭐ Great *by #***E on 10 January 2021* What an amazing controller. Saved myself the extra £40 by cutting off the end of two old hornby 16v ac transformers and wired them up. Obviously turn them off first. The slow crawl is better than anything I've ever in used.
