Vintage Synth Repair

I have done this multiple times for annoying synths using those two-prong modular cables. adding the IEC socket was a breeze using crimp connectors as it's usually an exact fit, and i have never had any problems adding a proper ground to the chassis. most rolands are VERY WELL grounded internally. its like the designers were terrified of RF or getting shocked or something. ;-) friend me on facebook if you want to see photos of my IEC mods and more... -pc
