BBC Micro - Power supply upgrade with brand new Meanwell PSU

A stock look with a brand new power supply for my friend's BBC Micro, let's hope it's good for the next 30+ years now!

The Mean Well RPT-60A fits very easily in the old housing, and costs about £25 with all the connectors.

Please do not take this as exhaustive instructions, and double check everything I suggest *yourself*. I am not qualified to tell you what to do. Mains power is dangerous, so be sure you are comfortable doing this work, and understand what you're doing. The colours of wires on your particular BBC may well differ so check carefully.

Below are the links for the parts:
