Rinnai P70EV-720 Transformer (B) 32e - Genuine Spare Not all transformer faults on the Infinity 32e are created equal, with some being the same on one component but different on another. This model uses two transformers, and getting the right one from the start is crucial. You want that transformer to be correct from the moment you place your order. The P70EV-720 is Transformer (B) - the second unit in the Infinity 32e's transformer pair. The transformer on this appliance has got a few jobs to do, it supplies several voltage outputs: AC 30–50V, AC 180–220V, and AC 12–18V to the PCB circuits, and when any of those outputs start to drift outside the normal range during a standby test then the transformer is the culprit. Transformer voltages are measured while the appliance is in standby mode - that's a important detail, not while it is actually w
