Could be a poor earth ground. Mounted in a car there is a bit more metal around it help stabilize it's metal cabinet to ground which you don't have sitting on the work bench. There also could be some effect between you touching the knob/chassis and the ant. This may cause cause the mixer/osc to pull a bit. These 12v HV tube or space charge tube are not quite as robust as regular tube w/normal hv on them and can be a bit squirrely
