In Reply to: RE: anyone have a crossover schematic for radio shack Nova8B 40-4026A ? posted by AdamC on February 21, 2014 at 04:24:19
I don't have a schematic, but it looks to me to be a simple 1st order on the mid an the tweeter, so you've got two capacitors per speaker and no inductors.

Lower right had portion, 1.4mH.

Not only is there an inductor, there is two! I did not look very carefully. Even with the two inductors, you just need replace the capacitors. inductors don't go bad and it can be a can of worms if you replace them.

Dave, where's the other one? I don't see it. But you're right about inductors. There's a misconception that if you replace one small gauge wire/iron core inductor with a fancy big bucks one with 10 ga. wire and an air core, as long as the value in mH's is correct, it will work fine.

The lower inductor has a bare copper wire, the higher one has a red wire.

The red lead goes to an RCA input jack. If there's an inductor in there, it must be about .0000000000001 mH.

OK, I see it. But they both look like black spools.

I'm glad we were able to discuss it as adults! ;-)
