When saturated - it does cause broadband diode noise.
http://www.iceradioproducts.com/reconly.html And the text says: Circuit uses a multi-stage design of transformer saturation coupling and current limiters. The best I can get out of this is that when the transformers saturate, they no longer transfer any increase in power. This is true, but they will also start to distort at the same point. Your step up - step down comment is interesting. The back to back diodes will start to conduct at some point like 0.3 volts, assuming germanium. They talk about 0.3 volt protection, which I assume comes directly from the diodes. If they did "step up", then that would change the impedance, the voltage/current ratio, and step up the voltage between the transformers. This would cause the effect of the diodes to be increased, since their voltage drop is constant. But, since they specify the voltage protection level at 0.3 volts, and talk about "saturation coupling", I'm gonna guess that they are 1:1 transformers. But, if they were step up/step down, then that would be a way to "adjust" the impact of the diodes by boosting the voltage (at the expense of the current), so that the diodes would start to conduct at a lower input signal level. Speaking loosely, this would make the diodes "more sensitive". >>>Saturation of too much power causes dynamic loss??? Yes, that appears to be what they are saying. When you saturate the transformers, you stop transferring power, at the expense of distortion. _______________________________________________ UR RST IS ... ... ..9 QSB QSB - hw? BK
