Hello Everyone,


Below is the original Philco (P-920) 1.5v size "D" batteries, that were used in the 1955 Philco TPA-1 and TPA-2 All-Transistor portable battery operated phonographs. These Philco phonograph models used (4) batteries in its circuitry, which the battery compartment was located at the very bottom of the outside of the phonograph's cabinet. You will also see these "same" batteries, that are pictured in Philco's "Publicity Photo" in the Popular Science Oct 1955 issue, that I have previously posted above onto this thread.

Below is a item called a Philco Stroboscope cardboard disk. It was used on the 1955 Philco TPA-1 All-Transistor phonograph, to adjust the calibration 45rpm record platter speed.
