Struck my first snag last night. As I said before the machine does not start. So I plugged it in, turned it on and started to have a bit of a look around. After a few seconds a relay somewhere pulled in, started buzzing, then smoking. Bother. (Turned out to be the 1st Ball Relay which was pulling in as soon as the power was applied. Not sure if this is correct operation or not. No schematic yet). Turned the machine off using the underneath switch. Then crack, pop, lots of smoke. Either the transformer or this thing (maybe a line filter ?) have died. I will not get a chance for proper look until the weekend. Disappointingly no fuse blew, either for the relay smoking or whatever else shorted.
More updates next week,

That silver box is the EMI Filter, and MartyJ and I watched one go up in smoke once and it was quite an experience !

You will need to replace the EMI Filter. Jaycar have a plastic version, but the version I use is a metal version from Rockby Electronics.

The 10Amp version is fine.
