40-190 hums intermittently

You might check if the nut mounting the volume control bushing to the chassis is loose. Sometimes if the case of the volume control is floating with respect to ground, a hum problem can occur. This might be the case as you mentioned that just touching the volume knob or shaking it can make the hum occur. It certainly seems that you have an intermittent loose ground connection somewhere within the audio circuitry.
