[Boatanchors] Where is C32 in the 75A-3?

[Jbrannig at verizon.net]

It has been a very long time since I owned or worked on a 75A3, but I 
remember going crazy trying to find that capacitor.
After removing the mechanical filter box I discovered that it was a fixed 
capacitor.

Rob -

According to my 15 APR 54 schematic, it is located off the Plate of V18, 
along with L-30, and is
shown as inside the filter box.  It's been years since I had an A-3, so 
don't recall if there is
an access hole to adjust it or not.   It's location on the schematic is WAY 
out of order!!
