Can't go too far wrong if you use 10 mf 450 volt caps for the filters, provided you get the polarity right, and pretty much follow the schematic already provided. Second one cn be 22 mf if there is any audible hum. Replace all the other wax capacitors period. Use 630 volt types. And be on the lookout for any burned up or out of tolerence carbon resistors as you go through the set, and replace any you suspect might be drifting. Better yet replace 'em all, cheap enough. Wirewound and candohms need not be replaced unless open or shorted.

Fire it up slowly on a variac or a dim bulb contraption and let us know what is going on.
