Scientific calculator restoration! Will her display shine again?

Video Description

Join me in restoring this beautiful 1980 Electronika B3-18А (Электроника Б3-18А)— the first handheld scientific calculator in the USSR! This unit came to us non-functional and missing its non-standard power adapter. Can we restore it? A vacuum fluorescent tube display has never looked so good!
