One of New York Parks 2-V PAM 19 In each of these other parks is installed a 2-V PAM 19, shown above, which supplies reproducers located at proper points, thus permitting simultaneous quality reproduction at widely separated points. The parks in your city are logical prospects for a similar type of equipment. Have you seen your park authorities? A new 16-page bulletin giving mechanical and electrical characteristics, representative installations, and many new PAM amplifiers will be sent upon receipt of 10c in stamps to cover postage.
