Hi, All !
I am going to build an amplifier using GU-46 tube. It is glass
pentode. You know in the tetrodes we need to use a shunt
regulator to cure the negative screen current problem.
But is it safe to use a series type regulator for pentodes ?
I.e. can the screen current be negative (at first sight it can't)?
Oleg -- Why can't there be negative screen-I in a pentode?
All the best,
Oleg
