Having swapped out the bridge rectifier for a high power one and used nice high grade thermal paste I was able to power up the PSU and sure enough, it worked, I can measure the voltages and the mains fuse does not blow.<\/p>\n\n\n

\"it's
It lives!! we have 12V coming out of the once dead bridge rectifier<\/figcaption><\/figure>\n<\/div>\n\n\n

Awesome, I’m really chuffed with this. So I assembled everything (about 2 hours) and powered her on.
Only to discover another fault… ARGH!!!<\/p>\n\n\n

\"no
Almost all the lights<\/figcaption><\/figure>\n<\/div>\n\n\n

Sadly, the -12V rail is dead… Now I’m imagining the worst, so I decide to check the -12V fuse and well, it’s blown. Upon checking someone has replaced the 2A anti surge fuse with a a 1.5A standard blow fuse. So I power off, quickly swapped the +12V fuse into it and sure enough the -12V comes up.
So I’ve ordered some 1.25″ long fuses with the correct rating and when they arrive we’ll resume testing, but I’m feeling quietly confident that we’re nearly there.<\/p>\n","protected":false},"excerpt":{"rendered":"
