Did you ever find the original style PS for Sigma...the one with all 3 headers in one unit behind the reels?

I bought a machine that is DOA, turns out the PS is completely dead. I took it apart and found one of the Rectifier diodes shorted as well as one of the IRF component. I placed an order for them and will see how it goes. These are far easier to work on than the machines that had a separate unit for each header.
