Germanium diodes with bias.

Ah... I didn't think about what type of front end you might be using..... I thought you were intercepting the signal off the last stage of a regular 455 radio, and sending it through a different detector, and then back into the same radio's audio stage.... Just looking at the effects of a different detector on an already assembled full blown radio....

When I was in school we had a crystal set diving a small tube amp and a giant old speaker, WOW! That was the best sounding am radio I ever heard.... Possibly because it had such a wide audio bandwidth on the front end, now that I think of it....

I bet your crystal set, driving a good quality audio amp, has quite the good sound quality.... Inherent in crystal sets...
