I recently picked up a 48k Speccy from eBay. It works fine but the PSU seems a little on the noisy side. I remember my old one gently humming back in the day but my current PSU sounds more like an electric razor. Any thoughts people?
It does sound like a transformer plate / lacquer problem,i have heard of people re-coating them in some cases but with the ZX psu i am not sure it is feasible as it has been a while since i opened one up.
With larger transformers they sometimes have bolts or a bracket that become loose and can be tightened,the only other thing i have known go wrong with a speccy psu is the large filter capacitor which had simply become dry jointed on the pcb.
Thanks for all the info and tips guys. I'm a bit of a novice when it comes to the electrical side of things. I'll have a look inside my PSU and see what I can do.
If you don't hear from me again, it's safe to assume I've blown myself up ;)

I've seen super glue suggested, though since that is slightly conductive I'd be inclined to go for cheap nail varnish or something.
You could try to bind them firmly together with a tie wrap.
Don't bind it on the coils, you might damage the wire or insulation.
