I am also thinking the resonations are being caused by a grounding issue. Try tightening the ground wire on the preamp. Does your turntables speed control also have a ground lug?
woofer excursion at start of lp
Hello and thanks for reading-
No matter which LP I play, my speakers experience excess woofer excursion at start of playback. It gets less and less noticeable as the lp plays, after only an inch or so of playing its gone - no more woofer excursion (IE: after the first track plays) I suspect its my cartridge/arm set up, but the tracking force is dead on. All else seems fine. Any ideas??? Thanks.
