I'll second that, Marco is very good indeed with anything turntable related.

I'm looking for a transformer for the PSU at the moment, I want something with 240V primary and 270-275V secondary. Anyone got any ideas?

Sorry, mate, you need a techie-type for that one.
Going back to your cartridge (for a second) if you fancy sticking to am MM instead of a coil, then I would recommend any of the Nagaokas shown here on the Musonic Styli site:
http://www.musonic.co.uk/
Click on 'Cartridges', then 'Nagaoka'.
Some of the more exotic ones there are really fab

Right, I've had enough of waiting for transformer manufacturers to 'get back to me'! (I was thinking).
When rather fortuitously, an email arrived yesterday with some interesting schematics attached. One of which is an intriguing take on the PSU I was thinking about making which uses a pair of 240:9V traffo's back to back, all the components seem to be easily obtainable 'off the shelf' items so there should at least be some progress shortly!
There is a name on the corner of this schematic, to whom I may be addressing some questions. Take a bow Mr Nick Gorham!
Cheers,
Mike.

Maplin doesn't supply the choke any more, but the same one can be found here

Its a C4S constant current source, it has two jobs. It isolates the supply from the rest of the phono stage by looking like a very high impedance to AC, and it provides a load for the VR regulators to work as shunts.
What phono stage do you intend to use after it? As if its the one I built that supply for, that also has CCSs in the first anode load, and you may have trouble finding the depletion mosfets I used in that position, so you may need to use two more C4Ss anyway.
