On the original carboard caps the leads coming out of the 3uf cap are both orange and the leads coming out of the 8uf cap are both green. So, how do goes to a connector marked '3' on the alps pot and the other one goes to a punch down.
Does it matter which lead goes to to what ?
I am excited to refurb these crossovers as the brilliance and presence controls on the speakers do very little right now.
So. I plunked those caps into those speakers. I used a hair dryer on the old caps and between the glue melting and the wax of the old capacitors melting that was quite a mess. I secured the new caps to the board with wire ties going through drilled holes and used heat shrink on the exposed wires and 3%AG solder (for fanciness).
The speakers sound better than before. The presence knob turns the tweeter right up into the pain zone, I still can't tell what the 'brilliance' knob is doing. However, it's not the first time that I have failed to recognize brilliance!
Anyways, without squinting, I can say is that the speakers have better treble and more of it, and they sound more stereo. They may also have more bass now. They sound a lot like newer JBLs that I have heard and they sound very modern for a loudspeaker from the 70's.
