I have a PB 12 sub that was sitting idle for several years (it is basically brand new in the box!) I finally got around to finishing the room that it is set up in and hooking it up. I turned it on, and the two green lights came on for a second and went out. After taking it apart I noticed that the 2amp fuse was blown. I replaced it and it blew immediately. I even tried a 4amp fuse (all fuses were slow blow) and that blew instantly. In a last ditch effort, I jumped across the fuse and plugged it in. I figured that whatever fried was the bad component, and i would try to repair it. the transformer became hot very quickly so i cut the power. I have seen other postings that state that there are problems with the amps in these. I called Harman and they told me that if I cut the power cord off and cut the paper cone out on the speaker and sent it in to them they will send me a new Sub 12(the new model as the PB12 is discontinued). the cost for the new sub is $200 - they are telling me it retails for something like $400-$500. Is there any way to repair the old unit before I butcher it up? or is the new SUB 12 worth the $$$. Thanks for the help.
