Ampeg tone stack modification

I'm just curious about one minor mod for the Ultra Hi switch circuit. You state replace ALL capacitors (c101-c104) with the silver mica 250pF? Or is it only c102 and c103? The reason I ask is because, I can't make it out, but the schematic for the V-4 shows that c101 and c104 have drastically different values than c102 and c103. I know the mod allows there to be a boost of a wider "high" frequency range (hence the 250pF value) but what of the values for c101 and c104? Do they also move up to 250pF in this mod?

Also, any word on the 7 PIN module you said you were developing? I'm super interested in that component!
