The record contains 3 TX-0 plug in bottle transistor modules. The modules are made up of 2 parts. There is a five pin socket with 4 transistors and 2 capacitors 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 brown. One of the bottles has a paper label with “B-22” printed on it. The other two bottles are not numbered.
