<div> </div>
<div>I imagine a big part of the sonic difference between the transformer-and-diode-ring modulator and analog-multiplier circuits is the nonlinear behaviour of the diode ring.</div>
<div> </div>
<div>If the transformers do not contribute a lot of distortion (assuming that in this application they are not driven to saturation), they might be replaced by opamp circuits without losing much of the characteristic sound. </div>

<div dir="ltr">hello SDIYers,<br><br>i'm currently trying to figure out how to get reasonably affordable transformers for a passive ring modulator.<br><br>i'm finding that terminology like "audio transformer" does not necessarily correspond to a 20hz to 20khz frequency response - and that those types of transformers seem quite rare & expensive. i realize low frequency is a perpetual problem in the x-former world, but it would be nice to find something that reliably reached a low of 100hz.<br><br>i was wondering if people had any go-to sources for the kind of solution i'm looking for.<br><br>thanks,<br>yAP yAP</div>
