I don't know of anyone who would be willing to part with their Peter Yanczer camera. There must be several out there? I think as far as replicating his design the two main things are the photo transister (photo diode) circuit and the Preamplifier. Both Peters book referenced above and the Link to James Hawes camera circuit talk about the photo transisters and diodes as well as the Preamplifier circuits. Jim Hawes had emailed me a couple months ago and said he had a working camera design using photo transisters. His email contact on his website is: webmaster [at] hawestv [dot] com I moved back to California from Virginia 8 years ago after retiring. I have stuff stored at 3 places. I think my copy of the camera build instructions is stored in a box with the 2 aluminum disks and motors I purchased from Peter. NBTV in UK have an audio CD which will provide an audio signal to drive a mechanical TV. I purchased their CD years ago but never used it.
