Hi,

I dont think there are any specific details of this device existing except the basic wiring diagram and pics that you have linked to. There have been reproductions of this device, and the people concerned would have made guesses as to how to build it in relation to spacing of the crystal to the coils, the inductance of each coil, etc. Pieces of germanium can be bought off ebay, and the coils can be wound or existing coils used. The germanium chip is under pressure via the screw, and this is an important point of its operation, I believe. The coil specifications may not be that critical. So its a case of using intuition to build it, so it has best chance of working for you, and therefore you become entangled with it, and it its operation.

This image above has been copied from the Internet, and I am not sure how the original version of the TDC-device they used in the Scole Experiment lookes like?  Maybe that image represents just the original version of the device?  I don't have first-hand information and I have had difficulties reaching Robin Foy and other people in the Scole group who are involved. If we build a replica of The Germanium Receptor -  according to my opinion - everything matters: Placemnet of the coils, their size, resistance, amplifier, conversion of the signal from analog to digital format (if this is possible)   etc.  My plan is  to build a replica of  the TDC device following the "instructions" as carefully and meticulously and I hope to find relevant, accurate and true information for that ( not suppositions). Modern technologies are also under construction, but as far as I know, those technologies  help mainly in signal processing and filtering  ( not improving the quality of the original signal).  Please see:
