Well, tonight I stripped the PSU down and there
aren't any filtering caps,
at least not the X type ones I'm familiar with. Instead the mains cable
plugs into a honking big sealed tin box that terminates in a 2 inch earth
wire and 2 spade connectors that the live and neutral hook up to. Said earth
wire is bolted to the chassis and joined to a similar bolt holding the fan
to the case.
Anyone seen something like this 'mains plug in a sealed tin box' arrangement
before? The thing's got to be 4 or 5 inches by 2.5 inches so whatever goes
on in there is anyone's guess.
Yeah, it'll contain class X or Y filter caps :-) Often the schematic for
what's inside the filter is printed on its case, but this one may well have
never had one, or it's fallen off.
It'll just be the same sort of arrangement as normally seen within a PSU, only
in a screened casing.
