That thread makes interesting reading and more than bit worrying. Did the 'how to change the G68 power supply' ever get written up in the Wiki? (I've just had a quick look and it's not obvious.)

It's a distinct possibility I may need to repair the power supply on my ageing G68 one day. Since the replacement power supply can be bought for �50 ($50+tax in the US), I would certainly want have a go at replacing it myself.
