At some time in the past someone tried to design and install a new power supply board. I'd say, "What an IDIOT!", but I know who attempted this and he was not an idiot. This ham (now SK) was a great DXer and a good technician. Why this was attempted I have no idea. Bill sent both of this CX7s down for repair. The first one was mostly damage to the front panel and some minor repair. I did have to use the meter from this radio to get it going since the original meter was long gone. I'd like to thank Bob Zaepfel for sending a meter bezel for this restoration.
This restoration required a total rebuild of the harness in the power supply area. Since the board that was installed was no where close to an original board I found an original board in my parts and used it. This board was missing many parts and some traces but it was a perfect candidate for the IC mods which remove most of the pass regulator parts anyway.
Here are some before, during and after pictures. The radio is now running with a few problems yet to solve. One thing I must do is build a new audio output module using an LM380 since the original parts on the power supply board are gone.
