Perfect for a vintage restoration or display of period semiconductor collection. Hard to find in the original packaging. You are buying the one pair as shown. Here is some history of the 2N697 HISTORIC NOTES: The unique history of 2N697 Semiconductor has been documented in a variety of sources. The initial product line, developed in 1957, was a high performance silicon mesa transistor. Initial shipments were made to IBM in 1958 for use as a memory core driver ($200 for each transistor). By 1958, marketing the transistor commercially as the 2N697. These were the best performing silicon transistors available at the time, and were very successful commercially. Other semiconductors companies quickly joined in, and the 2N697 soon became commonly available and were produced for many years by many companies. Early prices were quite high and made substantial profit for those companies capable of silicon transistor manufacturing. Texas Instruments, for example, offered the 2N697 for $28.50 each in the 1960 Lafayette radio catalog.
