Update:
I got the radio back from the shop again. It appears the speaker probably went out, as a new one was retrofitted in the tank, using the old transformer. I will test it again this weekend. I am sure other components were replaced.
As for the repaint, the restoration shop is unable to commit to the due date, and I am unable to find or think of anyone else local to do it. I can repaint it, but the tubes where the kickstand mounts need to be repaired or replaced while the bike is stripped. I do not know how nor own the tools to do brazing. So, in short, I may have to do my best and present it with the half-nude frame. I am not going to half-ass a paint job on a high end bike. I will still have this particular shop do the work, but it will have to be during the winter, after the show. I will not compromise quality over convenience.
