SRS gen1 crossover update question

crashb4

Guys,
I am conducting my due diligence prior to updating the crossovers on my SRS blade/blade. I have the list of required components and the schematic, but I notice a component that is referred to on the schematic that is not listed on any of the parts lists that I have come across. There are two 750pF caps listed; one that is wired in parallel across the 12uF cap and one wired parallel across the 22.5 ohm resister at T3 on the HF circuit. I have scoured the forum and not found reference to these two caps in upgrades or seen a description of their function. Nor have I seen them listed on any of the parts lists from previous update postings. I am no EE, but when a component is listed in a schematic, it is there for a reason. Can one the senior members here enlighten me as to the function and importance of these two caps?
As always, your help is greatly appreciated.
Mike

Those are Silver Mica bypass Capacitors. They were added to improve the performance of the Mylar Capacitors. They are no longer needed with quality Metalized Polypropylene Capacitors.
