Hi John,
The Avondale Stage One Phono Module is a convenient starting point:

This takes a pair of 322 or 323 boards on the normal Tyco pins used in the Naim preamplifiers. There are locations on the board for two regulators although I'm not sure what Les intended to use here. You could easily mount a couple of TPR2 or similar regulators just off this board and feed the box with 32 - 37 V raw d.c. from an external psu. There are also locations for an LED indicator, a ground lift circuit and input load resistors.
With local regulators and suitably modified 32x boards this should easily outperform a Stageline.

I use the 5 series cards. I have a DIY project (along with all the other!) strip board with pins to locate the cards. Powered by a TPR'd SNAPS ATM, but I'll make mono boards with a reg each, fed by raw DC in the future.
A worthwhile improvement on internal boards.

Captain, I highly recommend upgrading a Stageline N with Super TeddyRegs. It was possibly my most satisfying project ever. 
You'll want a more recent unit with 2 DINs so that you can separate power from signal. Then you can use a really cheap 31+ VDC supply like one of the HP printer supplies on eBay.
