May 1936 Radio-Craft Cover - RF Cafe[Table of Contents]

People old and young enjoy waxing nostalgic about and learning some of the history of early electronics. Radio-Craft was published from 1929 through 1953. All copyrights are hereby acknowledged. See all articles from Radio-Craft.

This is another Radio Service Data Sheet that appeared in the May 1936 edition of Radio-Craft magazine. I post this schematic and functional description of the Arvin Model 35, 8-Tube Car-Radio Receiver manufacturers' publications for the benefit of hobbyists and archivists who might be searching for such information either in a effort to restore a radio to working condition, or to collect archival information. 

Arvin Model 35, 8-Tube Car-Radio Receiver

(Push-pull output; tone control: highly filtered against noise.)

These receivers are designed for ease of motor noise elimination. In rare cases certain cars may be especially hard to work with. In such cases, the Service Man may solder a 3 1/2 in. length of shielding to the underside of the condenser pulley mounting bracket, directly between the 2 6/32 screws which hold the Bowden-wire housing clamp onto this bracket. The other end of this shielding is then hung over the edge of the chassis case on top of the copper-case ground shim, so that when the cover is put on, the condenser pulley assembly is bonded to the outer case. The usual suppressors will then be found to eliminate all trace of noise.

It will be noted that there are terminals provided for use of an external speaker, which may be of the electro-magnetic or permanent-magnet dynamic type.

A table is herewith given of voltage measurements as taken with a 1,000 ohms-per-volt meter;

C.-G. voltages are measured with a V.-T. volt­meter. Plus or minus 20 per cent is acceptable on all voltages.

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.
