Member Amyotte's reflex radio post has piqued my interest in building 1920's-style radios again. I'd like to build one myself, but I'd like to make it as close to 1920's authentic as possible (sans DCC magnet wire wire which seems to be practically unobtanium). Unfortunately, commercial fixed crystal detectors from that era seem to be scarce and expensive, and adjustable types are a bit touchier than I would like fora circuit of this sort. Does anybody know of any vintage plans/instructions for how to build a simple and inexpensive fixed or semi-fixed detector that would work well in a 1920's reflex circuit? Perikon is out, BTW, based on the expense of zincite crystals
. Would prefer not to go carborundum, either, as it needs a separate bias battery and potentiometer (and I have heard they aren't particularly sensitive, either).
