Hello Everyone,


I was searching thru my archive files and I also found an article from the New York Times, which was Philco's official announcement of its "NEW" Consumer product - All-Transistor Portable Battery Operated Phonograph (TPA-1). This Philco consumer product was also the "World's First All-Transistor Phonograph to be developed and produced".
