75µs uses all the caps:
The Left Channel is R4 & C9/10/11
The Right Channel is R5 & C12/13/14
Remember that there are consequences in changing out the filters. It will pretty much require an alignment after the change-out. There is one 3 pin and 1 4 pin filter in there. The 4 pin is equivalent to 2 3 pins. What Bill typically does is give you a matched set of 3 GDT filters, and with his adder board which has enough gain to compensate for the insertion loss of the GDTs. If I remember correctly the GAXX filters are GDT types.
I hope that makes sense.
