Arvin-Ford 17-A: A 2-way plug switch provides extreme sensitivity for country driving, and lowered sensitivity and reduced noise level for city driving. Tuning condensers and tuning mechanism float on rubber to prevent car vibration from detuning the set. Filter condensers are hermetically sealed. Noise-filter circuits are built into the set. The vibrator "B" unit is of the non­synchronous type; a type 84 tube supplies the required rectification. Field current for the dynamic reproducer is obtained by connecting the field coil directly in shunt with the car battery. A stage of tuned R.F. amplification ahead of the first-detector eliminates image frequency response. The oscillator circuit is tuned by a shaped-plate condenser.

Radio Service Data Sheets

These schematics, tuning instructions, and other data are reproduced from my collection of vintage radio and electronics magazines. As back in the era, similar schematic and service info was available for purchase from sources such as SAMS Photofacts, but these printings were a no-cost bonus for readers. There are 220 Radio Service Data Sheets as of February 2, 2018.
