The caps are almost certainly dried out - RJC = 1968 model (I have a wedgewood blue model with an RLC prefix, a couple of years younger). 43 is old in capacitor-years.
The axials up on end are originals - I had the same in my set, which had low FM volume and the ubiquitous hum. A recap solved all the problems, except one - the radio cannot pick up any quality broadcasts, just rap, Top-40, sports radio, and cookie-cutter country.
Cheers,
