Where/how/between what are you measuring the 110V ac?
So, it's a class 2 supply, so no earth - the pin is plastic. That rules out my earth being juicy - although earth and neutral will be connected together somewhere down the line!
It's likely just a bit 'leaky' - very low current. I do have other mains DC supplies that show 120vac, but they don't tingle 😉
Where/how/between what are you measuring the 110V ac?
Well, it's from the "ground" of the PSU, so it's irrelevant where it's measured on the VM side - but between the ground of the PSU and my house earth, first time round was a bonded radiator tail, thereafter direct to mains earth.
I've done some more probing(see what I did?) and I think this is probably a common thing from these cheap PSU's. Anyone wanna go measure theirs? Live mains leakage to DC ground - I guess mine is just a big more leaky than it used to be. Still, It's right next to my pc, so I'd much rather there was zero leakage!
Maybe report it to Trading Standards https://www.citizensadvice.org.uk/consumer/get-more-help/report-to-trading-standards/
