These were replaced with the proper value CE Manufacturing or Authenticap can type capacitors. These cost more but give the amp the proper factory look and they are used in the most expensive professional restorations. Illinois, Orange Drop and other quality polyester film or metallizied polyester capacitors were used where the original caps were polyester in order to preserve the original sound. The front glass is in excellent condition with no bubbles that I can see. There is some light pitting on chassis but it is not bad or about average.
It will provide you a lifetime of reliable service and great sound in it's present condition and you need not do anything.
