Yeah, oldest electronic, or oldest thing? I have a set of fireproof bankers drawers with a functioning rotary lock from like 1917. Oldest electronic… Do speakers count? I have a set of Acoustalinear speakers hooked up to a sound system… Or my grandpa’s old neon sign from the 1950s (although it has some newer parts… Ballasts and what not do not last for ever). I also have some old electric tube transistors in an old radio I restored that have “made in West Germany” stamped on them… But those might be from the 90s… I am not sure.
