I am looking for a site that has the schematics for JBL crossovers especially the 3143 or if someone has it could they post it or email it to me. I recently lost the link in a computer meltdown. I am building some JBL 4343s and just need the crossovers.

Thanks this is my first post to this forum.

Perhaps just providing a link to the existing scans already available here is better than posting an actual image in a message:
