But they'd dropped these by 2005 catalogue, in their phasing-out of stocking much in way of Electronics parts, before eventual collapse years later.

Yes I forgot about Maplin they were good for a lot of different stuff , I supposed they phased out stocking electronics parts as more people started ordering online including myself.
Its a shame they collapse it was good to pop in a have a look round and normally end up getting something.
I fired up my external power supply for my Triton project tonight and its dead, its a switch mode type that should produce +5 +12 and -12 there is no voltage on any of the three outputs. I have not worked on these types before so were to start fixing it is a good question and I don't have a circuit diagram either.
May its time to either rebuild the original Triton linear power supply, get a new switch mode supply or maybe use a PC power supply.
