Does anyone out there have a schematic for the older tube-type Sound Scriber circa 1950 (I think)? Mine is model LPR1KOS (5 tubes) in leather case with small lift-up front for loading blanks and accessing microphone.
Or does anyone know an Internet site where one can buy a schematic?

Generally speaking, there are two essential sources of service information for consumer electronic devices. Prior to model year 1947, the source was the Rider's Perpetual Troubleshooting (PPT) Manuals. These are MASSIVE binders of reprints of manufacturer's service data collected by the Rider group and published for service technicians. You can now find this data reduced to one or two DVD-ROMs from several sellers on eBay. After about 1947, the Rider service ended and that function was taken up by publisher Howard W. Sams. Sams still exists and has a website where you can browse for you model number. You may have to buy a compilation of data from them which will include many other models that you don't want. A third source on the internet is A.G. Tannenbaum:
