Early 50's Zenith hearing aid (electronics)

Postby martinw » Sat Sep 02, 2017 2:11 pm

When I told the missus I was buying a vintage hearing aid she had a fit and told me to go see the doctor!

It was originally because I thought there'd be some early transistors in them, turns out it has some very small valves in it, so it must be older than the transistor one :D

They're tiny :shock:

It looks like Zenith knew all about giving the customer a great unboxing experience before unboxing was even a thing! :D
