The Sprague can that you mentioned sounds like it was a 20uf and 40uf multi-section can. One terminal is the 20uf connection, one is the 40uf connection, and the last is the common ground. This would probably work well to replace your orangish cardboard capacitor if you hook the 40uf section up to the very first filter stage. I'm not sure if bumping up the value that much would be a problem with the 6AQ5 tubes or not (it isn't with 6V6 or 6L6 tubes) and it usually tightens up the low end a bit at higher volumes.

Well, C2 and C5 are showing 1.22V I don't know about C6 I'm guessing its high voltage 288V there?
Are the two with the arrows the C2 and C5 would you suspect?
