If you have the schematic showing the values,you should be able to trace out what goes where. Replace all the capacitors. New ones are much smaller and you will have plenty of room. Use 450 volt electrolytics and 630 volt coupling, bypass, etc... caps. While you're at it, you will probably find many of the carbon resistors have drifted way high. It's so cheap and foolproof to just replace all of them as well. Wirewounds or candohms do not have to be replaced unless they are open/shorted. The tubes are most likely OK if the filaments (the two fat pins) show continuity.
