Hello,

I am new to this site and I know that this section is mainly about radios. But, I could not find a section on phonographs- so PLEASE excuse me....

I am wondering if anyone has or knows of someone, who might have a 1955 Philco TPA-1 or TPA-2 All-Transistor phonograph that come out in the fall of 1955. Philco only made this item from 1955-56. This Philco model was the World's first all-transistor phonograph that was made. It was a 45rpm portable phonograph that operated operated on (4) 1.5 "D" batteries. The chassis had used (3) Philco germanium alloy-junction PNP type transistors in its circuitry, instead of vacuum tubes.

Thanks Rick

Renovated Radios do carry what you need. As for the voltage, a wire should be at least 300V-rated.morzh — 11:13 PM
