the reason why i ask this is because the grounding for the entire audio is isolated from the chassis & connected to the B- rail. If you connected the negative of that capacitor to chassis, that could be the problem.
regarding the volume control, if the ground connection on the wafer in the control is open, it can cause the same problem. you need to disconnect the leads off the volume pot & check for end to end continuity, as well as continuity between the wiper contact as it is moved from one end to the other. i have seem many bad pots cause this problem.

That 20mf ground is ok it's not on the chassis, I know there are the 2 grounds, chassis and b- . I'll check the volume ground, via the wafer. Thanks
