Analog Seduction is just trying to “Make Analog Great Again”  :-DD
Maybe Dave should copyright this slogan and make up some hats and tee shirts; then sell the whole concept to these seduction people. :-+

Am I missing something, or is that a piece of metal with an earth pin?

Back in the day, we did have Mains RF filters, which were about the diameter of a 400 gram instant coffee can, about half the height, &  had a power socket on top.
They had real filters in them, made up of L & C, so they actually did something.
It  was still a bit of a niche market, as not many people had any great level of RF interference on their Mains supply.

Their current capacity was very low, so a lot of them came back as "faulty" after people plugged their small electric room heaters into the "wrong socket".
All they were good for after that was the dumpster!

Yes, it's basically shielding over unused mains sockets :-DD

Too bad it probably makes fuck all difference in practice.

Sometimes I wonder if it's really just a member of this or similar forums taking the piss (and the money from gullible people). I can't help but feel a little jealous, but then my morals kick in.

Just looking at them on Companieshouse and so right you are.
They seem to do be doing very well out of it and any debt on their accounts seem small.

It looks like they are selling the stuff out of a great big mansion house on the maps according to their contact details.

They were selling the stuff in a property on Eastfield Road before the mansion house in 2014 according to Archive.org but they now use it for some leasehold business under different names.

I can't seem to find much on the property price of that Manor house.


Edit:
Apparently that mansion is for their "consultancy" where they do the brainwashing and my mistake there is another address underneath that I missed:

I was looking at some brand that makes contact cleaner for them:

I'd like to think so when that explodes.

"Because in all other upgrade fuses, the copper-based burn wire will degrade over time due to oxidation - silver oxide is a good conductor. And of course all HiFi-Tuning fuses are deep cryo treated!

Here's a joke: ... if it is going to affect the audiophools so much don't bother putting a fuse in there in the first place.

I'm not 100% sure, but it looks like the entire thing (pins and body of the plug) are made out of a single block of copper. If that's the case, plugging it in would instantly cause an electrical short, and possible house-fire!

They don't have pins for the live conductors, only for the earth.

Still, the way BS1362 sockets work means that using these defeats the safety features.

Perhaps that will result in some of these audiophools managing to Darwinise themselves.

In what way? The safety feature is there to stop kids poking their fingers in the hot sockets, and with these fitted those sockets are covered. You can get the same thing made from plastic that allegedly adds extra protection. Being conductive, these should be safer than not having them!

No, from that perspective this is far worse (assuming the floor is not metal). You only get shocked if current flows from live to a return (N/E). A metal block in the ground pin provides a highly condutive path directly to the return, making getting shocked or electrocuted far easier from sticking something in the live.

(Also assuming this thing can be installed upside down, but even right side up it still has a handle/knobby thing)

Safety plugs are usually non-conductive.... I certainly wouldn't trust a safety plug made of a highly conductive metal. Some earth connections may be worse than you think. ::)

Mmm, yes, fair enough. I was thinking it would like a protective ground on any appliance (where the appliance here is actually the hot sockets) rather than as completing a different circuit with the user routing to ground. For the latter, you could say that any water pipe or appliance with metal case is a hazard.

They are...which is why ground fault interruptors exist.

The HSE has issued a directive on those, saying they shouldn't be used, as

(a) None of them conform to the BS1362 size factors, which might strain the spring contacts, causing weakness and possibly causing an increased fire risk,

(b) The "earth pin" is easily broken off, leaving the safety shutters open,

(c) Sockets that comply correctly with BS1362 are not susceptible to little fingers in any case.

The german sockets really show their advantage here - there are small round platters with mechanically connected or rotating shutters available, which go right into the sockets and are almost impossible to pry out, at least for kids. Easy to retrofit for old sockets. It is common to use sockets with integrated shutters nowadays tough, it is even possible to just exchange the old faceplate on a couple of designs...
Title: Re: Audiophoolery: Mains RF Isolators
Post by: dmills on September 05, 2020, 06:29:35 pm
ALL UK 13A sockets have shutters built in (And always have) it is a mandatory part of the standard.

The cheap ones operate the shutters by the insertion of the earth pin (Which is longer to make contact first), the good stuff (MK) operate the shutters off the earth pin then simultaneous insertion of the live and neutral pins.

The fact that the 'Safety' covers defeat the BUILT IN safety interlock required for approval, and can sometimes be inserted upside down (Leaving the line and neutral shutters open and accessible) is what makes them fucking stupid.

These things might have made sense back in the 1940s and 50s when unshuttered round pin sockets were still commonplace, but they were always a stupid idea when applied to the 13A socket.
