Does anyone know if there are any plans out there for the circuit and components of this device? It converts Hz only from 60Hz Input to 30Hz Output, leaving the voltage the same. I have one and it works. They were always available on eBay and other sites for 10.00 - 50.00 USD. Now they seem to be getting hard to find and starting bids are $100.00. They appear to have a Bakelite (sp) shell and are epoxy potted? The weight leads me to believe there is a transformer inside, probably a group of Diodes, and a some sort of load coil. The load might be the weight of the device. Since they were always on inside the KSU they won't last forever. Thank you for this group. If I posted this in the wrong area please advise.
