I have a JBL PB 12 v6 subwoofer. I was given it by a friend who said if I can fix I can have it or just throw it away. Well I am getting around to fixing it and here is what I know. The 2 amp slow blow fuse that was in it blew. There are a couple resistors that look burnt, and when I meter them I get a number for a second or so and then no reading. Not sure if my meter is not very good, or if the resistors are bad or I am just not getting a good enough connection to the leads. I put a 10amp fuse in an turned it on for just a couple seconds and the transformer starts to get hot and hum. Is there a chance that the transformer has gone bad, or is ti much current going through it because the resistors are blown? Lastly, are there other components that likely went bad due to heat and to much current? There appears to be a small transformer(which I don't think is for the power supply but actually part of the amp) that looks a bit stressed so I am curious if anything else could be damaged.
