Hi,
I would strongly suggest that you think about replacing the filter caps at the very least. If one of those shorts out, it can take out your transformer in a hurry. The filters are the 'main' capacitors that filter out the current in the power supply. Generally we will leave the old capacitor can on the chassis for looks, disconnect it, and add the new (smaller) caps under the chassis.
As you already know the set works, that is a good sign. So by replacing the filter caps first, then testing, you should at least have a more reliable set. But from that point, you should consider replacing the other caps too.
I am not sure, but your set might have bakelite block capacitors under the chassis. YOu can find info on this site and Chuck's site on how to rebuild them. They are pretty easy really once you have done one, your next ones go fast. You don't have to unwire the block either. I rebuild them left wired in place, shove out the old caps, insert and solder new ones in. Takes less than 5 minutes each to do.
Usually it is suggested that a new restorer replace one or two at a time, then test. If you replace all at once, and you make a mistake, it is harder for you to find your mistake. Replace one at a time, then you know where the mistake was. YOur static cold be cause by dirty controls. Contact cleaner made for potentiometers will clear up any static caused by the controls. If your set has pushbuttons, that is another place that poor contact happens, causing static. The bandswitch (FM/AM/SW/Phono, etc) is another place that poor contact happens.
Good luck with your set,
Gary
