I've been curious about moving coil cartridges, and when the PX-3 I bought a couple of months back came with one, I started getting serious about it.
I came across several projects involving Altec microphone transformers, seems that they are a great fit if you wire them up "backwards", so I watched ebay until I found the pair that I wanted.
Here's a site I like a lot, and the schematic shown as well as several examples of other transformers are shown: http://members.myactv.net/~je2a3/mic-mcstep-up.htm
Here are the parts involved, first the chassis, perf board, 8 pin sockets and RCA jacks.
Here's the pair of Altec 15095-A transformers
The ugly side, all wired up.
And the completed project. I totally horked up the cover so I'm going to fab one out of flat plastic and apply some veneer to it one of these days.
And it works perfectly. I have my Yamaha MC-705 dialed in and playing my Pink Floyd DSOM 30th Anniversary disc right now.
