I saw your replies this morning and searched online for a RANE power supply as I could find nothing for the JBL SPP-SWEQ.I just purchased this: (https://reverb.com/item/65477662-rep...30-more-fx-rs1), from Reverb.It was a better solution than attempting to cobble one up from random parts scattered in various boxes around my shop or risking another purchase from eBay.(I did find the same item on Amazon, but the one from Reverb had free shipping). Thanks for all of the input and suggestions,pk
