CEO to the marketing Department we need to sell more 35W4 tubes. Yes Sir. Production this is the marketing Dept start using 50UF & 50UF no more 30UF & 50UF this is from the top!!!  Not trying to be a wise @&$ but do what  mike suggest.

Well like I said, Seeing as they don't make 40 or 50 MFD Capacitors anymore since they redid the capacitor values in the 1970s the next best capacitor that uses the modern capacitor value system is a 47 MFD which is what I ordered, if you tried to use a 33 or a 39 MFD it would be under rated for what the radio needed, if you tried to use a 68 MFD (if what you and morzh are saying is actually true) then a 68 MFD would be over rated, so I think a 47 MFD is fine in this application since the values they would of used back when this radio was built no longer exist since the capacitor value system redesign in the 1970s.
