1) Is blocking an issue with capacitor coupled cathode biased output stages?
2) Is there a way to DC couple a follower-type driver to an output grid in a self-inverting push pull output stage? See attached schematic. Please note that there is a cap upstream of the stopper resistor connected to the "upper" grid. BTW, the LM317HV is being replaced with a TL783. 700mA, 125V.
3)When using output tubes that require substantial grid current, is there another solution that can eliminate the coupling cap?
Respectfully,
Stuart
