Just recently, upon powering up my Bride of Pinbot, as soon as I flip the switch, the machine makes the loudest, God awful static-like "SSSSHHHHHRRRRRAAAAAAAAAAAA!!!!!!" at full volume and it scares the living shit out of me each time it happens. It also snaps really loudly when shutting the machine off. Machine plays just fine otherwise. None of my other pins even come close to making a noise like this. Do all BoP's make this noise?
