I am in the early stage of writing a history of the General Radio
model 275 crystal (piezoelectric) oscillator. I have one complete 275,
and parts to a second. The 275 was the first commercially available
crystal oscillator. I hope to restore both 275s to operation. The
paper will also cover the model 375 station monitor which followed the
275 and used the same oscillator. I have most of a 375, which I will
soon begin restoration. I am interested in any pieces of hardware,
including models 276 and 376 Quartz Plates, and any documentation (or
copies thereof) including the relevant portions of the General Radio E
and F catalogs.
