@mgattmch Good catch. I didn’t even consider the older Papst power supplies.
@boywondr84 Both of my links above are the newer DC power supplies,
@elliottbnewcombjr posted the link for the QC power supply which I believe is an upgraded Power supply for the older pre 2000(?) Papst AC power supplies. These are considered "vintage" so you can’t buy them new.
I find this reference useful: https://www.angelfire.com/music5/michell_gyrodec/ it may help during assembly.
Let us know how it works out. I’d especially like to know what year it is.
Good luck with the Gyrodec, you’ve got several Gyrodec fans rooting for you!
