paul's 5150 PSU mod from 110Vac to 220Vac.

Have the little EMI PCB done. My soldering skills have not let me down after 20 years.

I've removed the components from the large PCB and drilled the new holes in it.

Production must stop now as my wife is on holidays - vacation for those on the other side of the Pond - and I'm not allowed to "play" with my computers.

Up early today. Soldered the four diodes onto PCB and the two jumpers. Waiting on resistors and capacitors to arrive.

No PCB required. It's a simple mod if you're a reasonably skilled electronics hobbyist. PM sent.

No new boards needed. The instructions from paul are very detailed.

Just follow them. The hardest bit for me was soldering the four new wires.
