Memory transistor

A memory transistor is a miscellaneous quest item in Fallout 76.

Locations
The transistor can be found near a Mr. Messenger during The Messenger quest.

Behind the scenes
Although labeled a transistor, the item visually resembles and the designations refer to a real-world 6-volt octal (8 pin) vacuum tube. The designations of "6AC7" and "6Ж4" refer to two equivalent vacuum tube types in the North American RETMA tube naming convention and the Russian tube naming convention in Cyrillic, respectively.
