Vacuum Tube Circuits. This page contain electronic circuits about electronic vacuum tube or valve circuits circuits and schematics. Eight simple circuit power supplies for your workbench mainly vacuum tube based the power transformer is what isolates the output terminals from the line and makes it safe.
More often given as ms which are ma per volt. A vacuum tube acts as a voltage controlled current source or vcvs. If you can t find a particular transformer there are several alternatives among the circuits.
Like the fet the relationship between the control voltage and resulting current is expressed as transconductance g m i p v g and has the units of siemens s which are amps per volts.
