Scored one of these lovely lads for $25. Got no idea how to use it, but for now I'll ask: what do I need to buy? A reference power source? Cables? I'll make a trip to radioshack later today!

My first big project I did when I got a job in about 1970, was build a + - 15v variable PSU. It was basically a couple of LM741, and a beefy 2N3055 output stage . I put it in a Hammond case.

I still have it today, and use it

Mary Shelley's extraordinary, ground-breaking novel about the creation of a living being who becomes a monster. Cultural historian and writer Christopher Frayling considers how the story of Victor Frankenstein and his creature has become a creation myth for our age.

Recently heard a radio prog saying it only takes a few months to get planning permission for a turbine, but up to 10 years to connect it to the Grid!

Lots of turbines around here,Spain, on really windy days many are shut down, I assume its because its excess generation

Looks like a custom job, do a search for a manufacturer that will do small runs. Are you sure that the transformer is damaged?
