Technically, it's a simple matter of the outer foil acting as a shield for the inner foil. So, the outer foil should be connected to the low impedance side, or ground, to reduce noise pickup. Also I suppose in high voltage application it is better for a safety aspect to have the outermost foil at low potential should it ever get exposed from the plastic wrap.

Though its true, I've never given it a moments thought before now. None of my foil caps have these markings, so I've never cared about which way to connect them. Multicaps, for example, may not even have this kind of internal construction anyway.

Hi all, I have a VSPS in use with a goldring 1042, I am thinking of upgrading to a Ortofon Rondo Bronze and was wondering if result would be better by utilising Sowter stepup transformers with the VSPS or going the phonoclone build way.
thanks in advance

Personally I'm not a fan of step up transformers. A 10x increase in voltage comes at the cost of a 100x increase in output impedance, plus there's the issue of limited bass frequency response of the transformer.

Hi again, thanks for that, so in your view then I take it that a phonoclone build would be your preferred solution.

In fact if the Phonoclone build is compatible with a Rondo Bronze, it will also represent a considerable saving .

Rondo Bronze: DC impedance 6 ohm, 0.5 mV output. The impedance is low enough that it would be a nice match for a step up transformer, but it's also compatible with the Phonoclone if you want to go that route.

Thanks again, considering that my funds will be severely depleted after the cartridge purchase I will go the Phonoclone route as it is the most cost effective solution
Cheers

I've finished my power supply. My first project of this type. I've used 50VA Amtek transformers at $17 each. The IEC connector incorporates a fuse and lighted switch to simplify my hole drilling and wiring. I have the IEC on what I plan to be the side for access. The umbilicals (or is that umbilici) exit the back. Comments and suggestions welcome.

BYW, how do you get the pictures to enlarge. The little thumbnalis just move a bit when you click on them?

@RJM, no particular reason for jacks, however, my TT has jacks too, makes it easy to record something with my DAC on the pc, which has jacks also.. + they're all Neutrik-brand too, which are decent connectors.
