REJUVENATION OF OLD PHONOGRAPH CYLINDER RECORDS

E&MP 93.004

Phonograph

September 26, 1940

Percy Grainger (left) noted composer listens as Elmer O. Thompson, Philco Corpn. engineer demonstrates rejuvenation of old phonograph cylinder records.

Invented by Mr. Thompson, new equipment transcribes the music faithfully as it was recorded on the cylinder, in contrast to fading, gurgling effects of old tin horn phonograph machine.

Cylinders too frail to be played with scratching needles can be safely used with new equipment, which uses electric eye principle and has floating sapphire stylus in place of needle.

Negative Number 3107
