JBL PS120 refresh

Time has finally caught up with my favorite music sub(s). They lasted 30 years but it appears the electrolytics have reached the end.

I LOVE the sound of these subs on music, only bettered by the Servo subs.

Looking for the schematics so I can order new caps and replace them on my two units and a friends single.

Would anyone have the service manual or a schematic?
