Tnx all, so far so gud! just 2 more ques,

When using "tetrodes" what happends if u loose Screen grid supply?
(we all know if we loose plate supply, the screen will act like the anode
es draw excessive current)..
I have seen a circuit using a switching transistor on the bottom end of
the Screen (earthy end) es was refered to a EBS circuit..it lifted the
screen supply above chassie!!


es Can i replace a Si NPN transistor with a mosfet in the electronis bias
switching circuit es if so do we use "N channel" type say 160 volt 7 amp
type?? 73 de vk3pa
