Because of parallel feedback from GU-50 plate to 6P14P plate. With gyrator load output resistance of the stage equals to tube's internal resistance that is not stable and not linear. ...

... ratio. I think I will try with Triode first . :-) And as you suggested earlier, with a gyrator in driver circuit. Maybe I will try the Pentode mode once I get the circuit working. Should ...

Cool. I will wait with great anticipation for the gyrator circuit. I will take the B+ voltages into consideration if using the gyrator. So minimum of 300V for driver side. ...

So in other words we get higher linearity with a gyrator and also "less heat from resistor" and and less need for a high B+.... that sounds perfect. But it does ...

... and it has limit: tubes can't be used when possible anode voltage exceeds their ratings. Gyrator is a converter of one reactive resistance to another. In our case it converts capacitive resistance ...

... it for my front end. How did you configure your 6P15P biasing scheme? Why do we want to use a gyrator instead of simple resistive loading? Better low frequency response?
