Folk,
A friend of mine designed the circuit below stating it can provide 0.2 ohm AC impedance, meaning it can replace both cathode R and cathode bypass capacitor.
This is similar to using LED or diode to forward bias the cathode. And the below circuit can provide much higher cathode voltage, in the below case, 97V above ground due to direct couple to 1st stage.
How would you describe such approach compared to typical cathode resistor with a big electrolyte bypass cap， in term of soundwise?
