I have stacked electrical item , don't you

Yes of course I stack items as can be seen from the photo. I do however take care to stack items in a way that they have the least impact on each other. Cyrus use non-ferrous case-work and are happy to be stacked. The Rega Phonostage is stacked on a non-ferrous case.

The Sky box is plastic, electrically noisy and in the main, unshielded (which is why I keep it the furthest away).

One of the advantages of separating the power supply, is to prevent noise from entering the system, so putting a power supply in a position that may compromise that will not be to the best advantage and would possibly negate some of the reason for the exercise in the first place.

Andrei, now that looks an interesting product and is a constructive suggestion. I will look into it, pity I don't read Japanese (or speak it for that matter). Before anybody gets clever, I realise that it could be Chinese.

Does anybody know about this, price, availability in UK for example?

Would this have to be earthed to work??

My parents had no end of issues with a sky box a while ago, so much interference on the stereo it was unbelievable!
I ended up cutting a piece of stainless and placing it on top of the sky box, this helped a little. I then drilled a hole in it and riveted a cable on that went to earth.
that made a world of difference!

True.

BUT 99.5% of that noise you are talking about is mechanical, not electrical. The PSU mod is about getting the transformer physically removed from the plinth. Everything else is a happy bonus.

I certainly get and understand the mechanical aspect, but IMO the electrical side is just as important. It is of no use to solve one issue and then go and create another.

Thanks for clarifying that , Also I had problems with a AT120e cartridge causing a hum , with the arm on the rest very slight hum , as I moved the arm nearer the record the hum got louder , Now I have a external power supply the hum has gone
