Hello! I have an R-112SW sub that has been working fine for 3+ years and recently developed a symptom where the cone pulses every other second or so with no audio input (sub just powered on, no other cables). When I do run audio through it, it sounds crackly and like crap. I've gathered from watching videos and reading up on this sub that this failure is rather common and likely due to one or more capacitors failing. I'm experienced with board level repair for pinball machines and have Hakko soldering equipment as well as a desoldering station, so I'm comfortable with doing the board work. My question is, tho, how the heck to you remove all this glue from the components and PCB? I've never seen anything like it - here's photo. Secondly, can someone provide a list of the cap part numbers that typically are replaced on this R-112SW board? There's so much glue on it, all of the labels are obscured. Many thanx, Kris
