It had me wondering... those Philco caps just look quite a bit more substantial than the garden-variety brown wax / paper cap of the same value and rating - and they are BLACK!!!.... There likely was a purpose to them - I can't see Philco going to an extra expense unless they had to. Perhaps Ron will weigh in on their significance... I had intended to replace them with standard mylar in any event.

I did take the grill cloth and hold it up to sunlight in the store to check the weave density... it looked loose enough to be acoustically transparent..... well, at least to my ears - 40+ years of rock drumming eventually catches up with you....
