This removal could in theory allow for hiss type noise in. Thanks for the heads up on this. I'm a bit rusty. Can you tell me what is the crossover point on a .1?? Thanks, Tweaker

no hiss , I mixed up hi and low pass.
it's part of a network. Simplistically, the 0.1uF cap in conjunction with the 470K resistor would form a high pass filter with a -3db point around 4-5 Hz (too lazy to calculate). However, the 47k resistor in series, in conjunction with the little pF value cap in parallel together form a low pass filter, apparently for RF, per TK's post.
