The record contains 5 TX-0 plug in bottle transistor modules. The modules are made up of 2 parts. There is a five pin socket with 2 transistors and 1 resistor 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 with a small yellow dot. All of the bottles have a paper label with a "T-#" number. The numbers present on the labels are 64, 104, 107, 102, and 75. The bottle number “T-64” has a paper tag attached to it which has handwritten notes and 2 transistors taped to it.
