in general? An friend of ours passed away who was huge into CB/Ham. I picked up various items from his estate including transceivers, mics, etc. One of the coolest units is a Swan 500cx transceiver with a 117xc power supply. Unfortunately, when I plugged everything in and flipped the switch, there was a pop, followed by smoke, a familiar site to any of us who worked on an arcade machine, I'm sure. I know nothing about these units so I'm wondering if anybody out there might have an idea what went wrong.
Any help is greatly appreciated.
