Philco 80 Jr, just starting....
#15

If you use too large of a capacitor as the first electrolytic then you risk stressing the rectifier and transformer (higher B+). As LASJayhawk mentioned, I don't think those 16uF caps are original to your set. The other issue you have to consider is the line voltage is higher today, also contributing to higher B+ (stress on the rectifier and transformer).

Capacitors are fairly cheap and I'd just buy a handful of 10uF's to have in stock.
