I have a fusion nv-am25001 with a broken power and ground connection. this part needs to be replaced, but I dont know where to get the part from. I e-mailed the company, but I never heard back from them.
I dont think you're gonna find those parts anywhere but the manufacturer. They may not even sell them to the public. Your best bet is to let Chris at DB-r take a look at salvaging what you have.
but seriously, maybe try and find another one of those amps thats broken. maybe the parts you need will be good in it. thats about the only way to get parts for some amps.
