Sonora Tube Co.

Ad in Radio News; 11/1924, p.785: 5 types offered: 199, 12, 200, 202, 201A;
Also mentioned in Tyne, Saga...p.363 - but we think that an other company made them and they were labeled Sonora only.

Arcturus in any case was the producer of the DE-1 (127), RA-1 (AC48), RE-1 (180), RE-2 (181), SO-1 (AC40) and SO-2 (150) etc. in 1927/28. But Arcturus made also tubes for Crosley, Sparton (686) and Wunderlich.

Production: 1924 -
