Orange Drop Capacitor question

[Axtman]

What is the difference between 715P Series, 716P series and PS series capacitors? I am refurbishing a Hammond organ and am considering ordering parts from Antique Electronic Supply. Thanks.

Straight from the datasheet of the 716P:

Type 716P ORANGE DROP® is a high
performance version of the popular Type 715P. It
is made from polyproplyene and foil with copper
leads for the ultimate in high pulse current and high
rms current capabillity. It is a pressed unit for better
utilization of board space.
