I bought a used piece of neon from an antique shop in 1979 or 1980. It was just the glass and I was assured it would work. They told me to go to Claude Neon which I did. I got wire and an old transformer there. With the help of my friend Tom, we mounted it on plastic and hung it up.
A few years ago I got a modern transformer and connected it to Alexa so I can turn it on and off with my voice.
Sad!
