Thought you guys might get a kick out of this;
I bought this UV
sterilizer for $130 in 1981. As you can see it still works, though I'm sure the bulb is next to worthless by now.
It is also easy to see how simple it would be to make one like this for a lot less than $130 1980 dollars. LOL.
I believe it was among some of the very first ones made available to the average hobbyist, but I did have to wait for it to be made for me. It could have been made in someone's garage for all I know, but I do think the same company is still around in So. Cal, but can't recall the name.
