"There is certainly enough space to change the feedback connections from the normal second plate back to the first cathode instead of the first grid"Looking furter at the location of where the eq's are switched it look like the above can't be done.
ie. on wafer 1D the eq is inserted back into the circuit after the ouput cap of the phono stage connecting contacts 1,3, and 7 together.
This is a bummer :( Can't see a way of resolving this without affecting all other inputs unless I am missing something.
Only thing I can think of is to eliminate one of the wafers that short the unused inputs to ground to pick up a spare set of contacts.
