We obtain tubes from all over the world. Some in this video came from The Netherlands, and others came from Pennsylvania! We buy bulk lots of new old stock tubes all the time from many different sources.

I like the 2N3904, since it doesn't need a heater voltage.

I work at an electronic recycling plant, I was able to get a few hundred tubes out of there...but the world needs to know that electronic recycling we break working antiques all day long
