If you are looking for a source for parts then this http://www.tuberadios.com/capacitors/  is a good one. Most of the time I'll get a sack of 25 caps of a given value not so much the onezy or twozy. If you are a stickler you can restuff the foil/paper caps using some brown colored hot glue in the ends. You may want to grab some wire too as your set has the old failing rubber coated stuff. While you are replacing the caps it's a good time to measure the resistors and replace the bad wires. I typically will replace all the rubber wire that carries the hv some do all of the wire but I'm lazy.
