Mystery Caps in my amp??? need help

[lustandfury]

I have a Garnet Rebel II that seems to have two extra caps not on the schematic. They appear original, but in bad shape and need replacing, they also seem to be in a strange section of the preamp. I may have it wrong. Any help clearing this up would be greatly appreciated! Below is a photo of the actual amp and where it appears the extra 100 uF caps are. The one circled in green is the only such cap I can find on the schematic. Thanks for any help in advance!

First off they are 100 pF (picofarad) caps not uF (microfarad).

They were added to either reduce the possibility of radio signals from entering the pre-amp, or to reduce the possibility of high frequency oscillations in the tube stage. At that value, they will have a minimal effect on the audio portion of the signal.

Hey Bill thanks a million. I'm still a bit wonky o the pF/uF measurements. It's been driving me crazy! Does it seem like I have them marked at the right place on the schematic?
