Definitive Technology SuperCube III 120v Subwoofer (Single, Black) (Discontinued by Manufacturer)

okay so i have a customer that sent me a definitive technology power field super cube 3 subwoofer this is just the internals he didn't send me the speakers looking down in here right off the bat i see a bulged surface mount cap right here so i haven't even hooked it up yet done any tests so i thought the first thing i do is go ahead and try to esr all these capacitors and see what they look like before i go any further bunch little caps on this board we'll check all of those main filter caps over here 1500 microfarad 200 volt capacitors because i believe this thing is a digital amplifier that probably runs off of the ac input i don't see a switching power supply anywhere in this so let's go ahead and do some esr checks on all these capacitors and see how they fare okay so i've got the capacitors marked on this board the main filter caps 1500 these three or 220s might be kind of hard to
