I assume you are referring to C7, C11 and R12 as shown on the WE schematic on page 1 of this thread. I did not use any of those parts. I intended to try them but frankly never got around to it. I read somewhere that many WE 124 amps came from the factory without that network.@Salectric
Did you modify or eliminate the original EQ components since they appear to have been output transformer specific?
