Altec N809-8A Crossover network help

[christapleton]

Hello there fellow audiophiles. I have a pair of A7-500-8 VOTT's and everything is original. I need to refurbish the crossover networks (new attenuators, 1/4" jacks, various components of the actual board) and am wondering if anyone has done this and is able to give me some direction. I have found some schematics but without proper parts, Im hesitant to tear them apart.

I have not worked on those, but if they are like most old Altec crossovers the caps need replacing. The schematic says the caps are 18uF; here are some decent replacements:
