KG-13

The KG-13 was the first transistorized cryptographic machine developed by the NSA in the early 60's. It used the newly developed 2N404 germanium transistor instead of vacuum tubes. It consisted of a KG-3 transmitter and a KG-12 receiver. The transmitter used about 500 transistors and the receiver about 300. The transmitter was switchable to function as a receiver. (Wikipedia).
