Home Tube DIY Asylum

Do It Yourself (DIY) paradise for tube and SET project builders.

Opinions are like ten toes and ten fingers..We've all got em!

but....IMHO the higher the transconductance the better the suitability of the tube. Tektronix used cathode followers as input stages to oscilloscopes. They invaribly used the 6DJ8 and Nuvisitors, even a 6ak5 pentode. Pentodes need to be investigated as good cathode followers; 12by7. Good luck! Ray

And make of you what I will,

Non-survivor.
