Great pictures Louie! It really is in amazingly good shape overall for being 53.
I'd start out by pulling out the chassis and cleaning everything and getting familiar with the lay of the land. Look at the tube labeling and try to determine if they are originals, if so it may not have a lot of run time. Go through with a DMM and measure resistances to insure they haven't drifted off too badly +/-10% of the schematic value is reasonable. When measuring resistances in circuit, be aware that other parallel paths through the circuit could add error to your measurements.
I'd wager that the only capacitors that you should initially replace are any of the electrolytic units, while I would likely replace all the cylindrical paper capacitors eventually, they aren't highly likely to be "bad" to the point of causing a problem. It looks like the electrolytics are C70, C71, C73 and the quad-section can C83. I would replace the can with 4 separate capacitors under the chassis if there is room to tuck them in there. There are some reproduction twist-lock can caps today but there aren't many choices in value's. The NOS parts are just old now so they are likely bad before they were ever used. I'd leave the can there for looks.
Personally I would have trouble simply restoring one of these, I'd just want to resto-mod it so badly. I have long been POoGE'ing (Progressive Optimization of Generic Electronics) classic HiFi gear. I'd end up swapping out all the speakers and would likely swap the tube rectifier for solid state etc. Speaker technology is so much better today then 50 years ago, but then again it would lose that character that it had in 1963. It could easily be made more accurate, but that may not entirely be the goal, some might say this would ruin it.
Best of luck with the project, there are a few folks here glad to provide advice and moral support as you go!
