Product Overview
Desription courtesy of the Transistor Museum:
"The 2N63, 2N64 and 2N65 appear to be the first Jedec “2N” numbered transistors to be sold commercially by Tung-Sol, and the preliminary data sheets for these devices are dated early 1957. Note that Raytheon had introduced these “2N6X” numbers in 1956, so Tung-Sol should be considered a second-source supplier. The 2N63, 2N64 and 2N65 are similar devices, varying only in power gain, with the 2N65 having the highest gain. A striking feature of all Tung-Sol transistors is the beautiful “Robin’s Egg” blue case color and the brightly decorated cardboard packaging, as shown above. "
