43X Electrolytic Condenser help - Masonparker - 01-25-2021

I'm down to replacing the (3) Electrolytic Condensers  Items #'s 47, 72 and 75.  I need help confirming the polarity of the condensers . I have attached a marked up schematic to show you what I'm thinking.

Item numbers 72 and 75 I'm using the 8 mfd. since this is a two speaker set.   Center lug is (+) and the side post is (-) .  The side post is connected to both cans.

Item 47  I'm guessing it's a 6 mfd.  I found this on the Philco Library  but the years listed was from 1936-1939 . Since this is single lug  (+)  and the schematic shows this connecting to ground (-) would this be the correct way to install the new condenser
