I've heard good things about the Solens, but you can even find those generic yellow polyester caps in 1 and 2 uf 630 vdc sizes these days, I don't know if they go higher then that. Another option is a series of Panasonic film caps that Mouser sells, those go up to 3 or 4 uf, at 630 vdc, and are fused so they won't short out. I can't remember who made them but there was a type of film cap that Bob Andersen used inside the filter caps of his Philco 115DX, they were like red or brown drops, which he connected in parallel to add up to whatever he needed, but those were Mershon cans so they had the room inside. The point being is that thanks to improvements in materials and manufacturing processes, you can make filter cap changes a thing of the past in many pre war AC radios. In something like this Echophone, or the similar Dictator (Gloritone clone) I have why roll the dice with an electrolytic when 2 uf film caps are relatively inexpensive and available?
