Crosley Roamio 4-A-1: A self-rectifying vibrator "B" unit is used in the power supply of this receiver. High gain in this receiver has been achieved through the use of high efficiency R.F. and I.F. coils. This set mounts under the cowl section of the car, with the dial visible below the instrument panel. Thereby, the lid is easily removable for convenient service.

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.
