The record contains 28 TX-0 plug in bottle transistor modules. The modules are made up of 2 parts. There is a five pin socket with 1 transistor, 2 resistors, and 1 capacitor soldered to the circuit side of the socket. There is also a clear plastic bottle that screws onto the socket and encapsulates the soldered components. Seventeen of the bottles' tops are painted black and all but one have masking tape around the top of the bottle. Eleven of the bottles' tops are painted black with a white "X" mark. Twenty seven of the bottles have a paper label with an “R-#” number. The numbers present on the bottles are 52, 109, 118, 4, 6, 14, 36, 37, 39, 40, 45, 65, 72, 80, 81, 97, 114, 138, 144, 3, 7, 44, 55, 78, 101, 107, 117. The module that is not labeled with an "R-#" has a black painted top.
