That was my original TX102 based pre-amp kit. About 1/2 were sold as kits and maybe 1/2 were built here. I can't recall the exact history of that unit but looking at the pics it has 3 rca inputs and 3 xlr inputs + a single rca and a single xlr output. Almost certainly MK I TX102 transformers. Should be a decent sounding unit I expect. Price will look good vs the S&B based Music First units - but at 750 UKP it is maybe not far off the original pricing. No remote control - and it would be tricky and a bit of work to add remote to that unit.......
Hope that helps!
