Tingles from power supply

My guess is between 10pF and 100pF; measure it on a "free" transformer: between a primary wire and a secondary wire.

I have never seen a transformer type wall wart with a filter; the switchers are not so common and being newer kids on the block that tend to generate EMC, would have some kind of filtering.

Just a transformer type. No indeed.

The switchers are becoming much more common now.

Yes. Switchers are noisy, but I would venture that these small, barely capable types are even worse than OEM open frame or off-the-shelf types. They actually have a few design cycles in most of them. These El Cheapo mini-switchers are likely the biggest source of local noise around.

though.

And the connection with the disputed claim "most are not switchers" and "few are" is what exactly? And how does that affect his claim "All but the big name boys buy from an OEM supplier, and even some of the big guys do as well" in any case?

You might want to make that pretend bully boy. It does not intimidate anyone in sed these days. Perhaps the AlwaysWrong moniker we have given it is part of that.

Which I already mentioned as being one reason for switchers becoming more prevalent now the cost differential is small.

Which has what exactly to do with your claim "most are not switchers" and "few are"? That is what I disputed, not some new load of total irrelevancies.

But frankly I seriously doubt if you could tell if a handgun had one bullet in the chamber or was empty anyway. I'd really like to see you place it to your head, decide if it was empty, and pull the trigger based on your guess :-)

Picking a switching power supply is childs play by comparison, but was never in dispute.

Feh. You irritate me here. They evaluate existing knowledge and experience and set standards that we may venture beyond at personal liability risk. Same with UL and many other safety standards. BTW UL standards, like many others, are being harmonised with IEC standards. In my lifetime i expect UL and ANSI and CSA to be no more than the locals of standards.

"Most are not" leaves a few that would be . One remark is not negated by the other.

And these total retards call me a troll. You do not know the depth of your utter stupidity.

Reply to
Archimedes' Lever

Why? Because you THINK that shipping them would be that much greater?

That difference is not offset enough by the difference in cost you tout.

I would typically test such an unknown on a dope like you.

It does mean that we all know the depth of yours, DimBulb.

If he didn't spread it out it would quickly reach critical mass, and he would explode. Like nuclear waste, you can't just keep it all in one place. :(

One of these days he's going to slip up. Then there will be a sickening bang, and infected, rotting troll guts will cover half of California as their TV talking heads scream 'Earthquake!'
