I agree , analog ice is smoother and improves taste. Refrigerator beer is cold and sterel.
If not, then placing a capacator across the contacts useing a 1000 ohm resistor, coupling the transformer with low capacitence ossolating wire, while jumpering the windings and lowering the superheat of the suction gases well in effect cause a head pressure by-foobulating modulation. This in itself well induce a grounding phase loop resistenant to any ossolating modulation.
Hope this helps...
