After swapping the dead -12V 2A fuse, I powered it up and everything stayed on for about 30 minutes. So I decided to attach the monitor, keyboard and alpha-numeric keyboard and see what happened and sure enough, we have life! Super exciting! Keep in mind this Fairlight hasn’t been powered on for over 20 years!So next the big step, let’s insert a system disk, now I’ve no idea if the disks still work or if the drives have died (I can hear a motor but that’s all), and as I say, it is 20 years old. Yes! it booted much to my amazement, and what’s more I can even load…

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

I finally decided I could no longer avoid removing the PSU from the case to check the capacitors, rectifiers and transformer.Now if you recall I had a problem with the scan of the service manual in that the colours of the wires were not clear. I asked on the facebook group and David Cilia kindly took a photo of the area I was interested in and it’s so nice to see the colours. David also sent me pictures of the full page (left hand side and right hand side), Peter Welik also sent me another picture of the page I needed, wonderful! So please give his web site some love,…
