The main issue will probably be the wiring, I'm not convinced that changing out the mica caps is really necessary. In spite of what they claim on the barking dog forum I haven't experienced any more problems with those black, coffin shaped, mica caps then I have with any other type, so unless they are falling apart, or every other more common problem has been ruled out, I leave them alone. So what is the issue with the speaker? I see that the grille cloth is torn a bit but was the cone damaged too? To me it looks like a very restorable set, even that cracked veneer on the shoulder doesn't look too bad, though I wonder why RCA's cabinet makers didn't just use a single board from back to front rather then using laminated stock? I guess it was to use up left over material?
