hi im trying to fix my crack amplifier and everything was fine exept for a small hum so i started reheating the connections and now  the resistance is wrong at the right RCA cable. the red cable has 0 ohm but the white cable is fine(100k ohm). i went back to the manual and started rechecking everything but I couldnt find a mistake.
I drew the potentiometer and the resistances i hope it makes it more clear. thanks in advance.

You probably created a solder bridge from the center conductor to the outer conductor of the red RCA jack when you reheated those connections.
