anonymousRe: Removing Corona Dope?
"We have an amp here that has some corona dope on the PCB."
Corona Dope? Isn't that just a high-voltage insulating "varnish"?, or is it more like a potting compound? I guess my question is - why do you need to remove it? I would try Naptha or M.E.K. and if that doesn't do it maybe some JASCO or other brand Paint & Epoxy remover. If you just need to expose the PC board copper an exacto blade can scrape through most compounds.  
While we're on this subject - does anyone know of anything that will remove the green "solder-mask" found on the foil side of most pc boards these days? That stuff is tough and seems to resist everything except an exacto blade.
