The record contains 20 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. The top of the bottle is painted blue. All of the bottles have a paper label with an “L-#” number. The numbers present are 235, 279, 300, 304, 131, 152, 162, 196, 206, 239, 248, 270, 276, 277, 286, 287, 303, 306, 323, 363. Bottle L-300 has an additional label that reads "n/6 From F1(5 or S) L22."
