This series transistors were used in the transmitter of the artificial satellite who were taken out to the orbit of the Earth in the USSR in 1950s. A Museum exhibit! All the transistors were manufactured in the Soviet Union. We made photos of the last P2B vintage transistors from our set. The transistor is completely new in paper envelopes which were made a lot of years ago. The item in the photo is fully consistent with the original that you will receive in the parcel. We send one of the envelopes you see on the photos. If you are interested in additional details, please contact us and we help you select transistors and send additional photos.
