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.

These values are measured from the point indicated to ground and are read with a 1,000 ohms-per-volt meter. The line voltage is 117.5 V. 'The oscillator plate is 170 V. "This value is measured across the filament terminals. The voltage across 'the speaker field is 70 V. To align the I.F. stage, set the receiver tuning condenser to minimum and adjust the oscillator trimmer for maximum response, then adjust the broadcast antenna trimmer likewise.

Be sure to choose the minimum peak capacity on the oscillator trimmer. The broadcast band is aligned with a 200-mmf. condenser in series with the antenna lead. Set the receiver dial pointer at 600 kc., and adjust the broadcast series padder for best response. Move the pointer to 1,600 kc. and connect the output of a service oscillator to the cap of V1.

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.
