Google Digikey or just radios (canada) or for that matter capacitors. I get most of my stuff on ebay from sellers with good feedback. Newark or mouser, all electyronics are also good sources. Don't buy any old used junk from anyone, the stuff you will get will probably not be in any better shape than the ones you are replacing. Think about the other things you need/want, so that you can meet the minimum order and are not burdened by excessive shipping charges.

There's tons of information in this forum and elsewhere how to disguise new components in old cases, if you want to preserve the original look.

Above all, you must be patient. I spent an hour yesterday dismantling a 4 section can capacitor, stuffing it with new components, and getting it back together so it looks the same as it was to all but the most critical eye 60 years ago. This hobby will test your mechanical, intellectual, and resourceful energies more than you think.

So far as Radio Shack is concerned, beware there are people who are trying to make a living there who have never seen a typewriter, a vacuum tube, a punch card, adding machine, and would probably think a Weller soldering gun would be a prop from Star Trek, which Grandpa used to watch when she was a little kid. You could ask where the little yellow thingies with two silver legs that cost very little, and old men grunt and pick at, mutter under their breath and then leave without wanting to buy a new cell phone. Then, you will be directed to the corner in the back, where even the security guard does not watch you.

I'm sure others will chime in.
