Hi, I'm really struggling to figure out something so I thought I should ask here.
A tweeter in my NS-1000 stopped working. I'm pretty sure it's the crossover because I soldiered it in the other speaker and it was working there. It's also probably not the L-pad because I connected it to the cables that connect to that too, with the same result; the tweeter works in one speaker and not in the other.

I don't know how to test each part of the crossover to find out which one is faulty but from what I understand there are just 3 capacitors that connect to the tweeter so I could just change all of them and be done with it? The problem is that I don't really understand schematics and have basically no idea what I am looking at when I NS-1000's. Can someone tell my what specs the capacitors need to be and which ones in the crossover I have to change them with?
Thanks

The silver 6+1 are the mid range caps, tweeter is the grey 2.7uf and bass, 94uf is the two black caps.
 
Yep, that 2.7µF capacitor should work just fine for the tweeter. The R1021 and L1021 are probably part of the attenuation circuit, helping manage the signal to the tweeter. Looks like you’re on the right track.
