phonogfp Posted February 12, 2021 Share Posted February 12, 2021 "On This Day in Phonographic History..." February 12, 1903: Eldridge Johnson filed for a U.S. patent for a tapering tone arm. The acoustic improvement over the short-lived “Rigid Arm” (introduced in October 1902) was noticeable, and the ingenious goose-neck sound box tube would distinguish Victor products for decades to come. #antiquephonographsociety #phonograph #gramophone #antique 1 Link to comment Share on other sites More sharing options...
