  • I am wordy and frustrating EAYOR
As if who could forget . I ask this one question. One mod was to add a small cap across either of the 100k plate resisters for the 12ax7 to tame some highs . Now if the filter cap size has no affect on tone and since the 100k ohm plate load resister is off the B+ rail where is the difference and I am only going by common sense here not facts . Is it because a cap across the plate load resister is down stream and affects the the freq response of the plate on the 12ax7 . Is it because low frequency passes through a resister easier than through a cap?
