Lee-New to KEFs. Bought recap kit from Falcon. Found some caps out of tol so reluctant to use. Originals measure closer! After inspecting SP2011A board, I now suspect woofer prob (no sound) due to board etching degradation under C4 and C5 caps. Best to jumper around bad etching. How do you recommend I disable prot cktry to minimize interaction with speaker sound? In normal operation, does relay shunt R1 resistor?
