I used safety capacitors (Y2-type for line-to-ground) in mine, justradios.com recommends them for this application. Easy process, except somebody at some point put so much solder on that it took quite a while to desolder the terminals. When I finally got the thing out of the chassis, the solder pen had gotten the whole condenser warm enough that I didn't even need to use a heat gun to get the tar plug out...just stuck a straightened paperclip inside and the whole thing came right out.
