Saw a burnt spot on this cap, and took it out...
The schematic shows a .01 should be there, but this looks like a 100pf...
Can anyone verify this is a 100PF?

Looks like 100PF to me.

100 picofarad, silver mica capacitor, and they rarely fail.

Most likely 100 pF, but could also be 10 pF. This is one of those infuriating things about the numbering codes used on micas. On some micas, 101 is 100 pF and 100 is 10 pF. On others, 100 is 100 and 10 is 10.
This "looks" more like one that I would expect to be 100, but it might be good to confirm with a cap tester. A 10 pF is usually physically smaller with finer lettering.

I am sure that this one is 100pF, because of the literal +-10% tolerance mark. All of the "two digit plus multiplier" silver micas I have seen have the tolerance as a letter (J or K usually). So, I have seen some marked "101J" or "101K" that are 100pF. A "100J" or "100K" would be a 10pF capacitor.
