  • Notes

  • The Sparton model AC-62 was replacing the AC 6-15 in October 1927 (with the same price). This is according to "Radio Manufacturers of the 1920's", volume 3, page 118. By the way: The AC 63 is an AC 62 in drop-front cabinet, with minor chassis changes.

    The schematic is common for three models: AC-7, 62 and 63. But only the AC-7 has the two C-171 in parallel, the table models 62 and 63 employ only a single output tube. The circuitry is the same, except for the 2nd tube C-171. The second chassis for the "Transformer & Rectifing Unit" (spelling error in the schematic) is not counted for its tube.
