The nady is toast, I bought a Kenwood eq. tonight off ebay $55.00 After putting them back together I couldn't get them to sound for crap, and I had both the gain knobs at 0 then I noticed that the left side lights weren't going as high as the right side ones so I upped the gain to the 3/4 mark for that side and the speakers came right into tune. I've read up a lot on them since I started suspecting it was bad. I wont toast the next one, if it isn't already.
I have the entire parts list and schematics to build new N-1500 crossovers. Thanks to Mr. Markwart, and Abe.
