This homepage is
dedicated to electron tubes, strictly speaking electron tubes technology.
It seems strange because there is no tubes manufacturing in Poland. It
so happened that I accepted a challenge to design and make vacuum tubes
by myself. Here I present some results of my experiments under the name
of Private Tube Manufacture (PWL), which is in fact my home laboratory.
Tubec technology is connected with vacuum technology.
That's why I'm intrested in vacuum technology. There is some instructions of vacuum gauges, vacuum pumps etc.
