keen making at home what big producers with big means do... the right
tool, some ham ingenuity and a good knowledge background can do a lot!
Stefan in your qrl you can find a lot of tools ready for more than few

Hi Andre,
Thanks for the images, they are very nice! Maybe i will start some
experiments with tubes some day.
At work we've done some simple experiments with car bulb (glass body
destroyed) burning in vacuum (arround 1E-8 mbar). We applied about
120V
between the filament and case and actually got an emission current of
a
few 100 uA. That was exciting :-)
