I have found that some cheap (especially OLD) transformer V out is
heavily dependent on device current draw. So when there's little
current draw, the V can be VERY high (I've seen 1.5x - 2x higher than
rated on the case). Also cheap transformers are exactly that -
transformers - with very little regulation or ripple control.
Does the transformer say it is regulated ??
One other thing I would worry about is the MAX current capacity. The
replacement transformer may not have the current capacity of the
original. The way I understand it, these ion generators are very low
current devices. But even so, many 12v, 14v transformers seems to be all
lower than many lower V transformers (I'm not talking about those heavy
duty car battery replacement units).
So check the ion generator requirement and the transformer output capacity.
