The Aerovox can pictured is an older replacement, possibly from the 1940s, or early 50s, the original RCA caps would have been in bright aluminum cans, no label, and may have been wet electrolytics, or at least the input filter cap. Traditionally the value of the input filter cap should be as close to original as possible, within 20 % of what the schematic suggests, or a tube manual if you have one handy, but I'm not sure that this matters as much with model electrolytic caps.
Regards
Arran
