Ogg: Re: LF: Re: Make your own tubes for a LF/MF PA?
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
between the filament and case and actually got an emission current of
few 100 uA. That was exciting :-)
