Also, as a follow-up, I was trying to understand all the math associated with operating points, as well as resistor and capacitor sizing. Rather than just copy as design, I am hoping to understand and learn from the design. Apologies for the simpleton questions ...
For the driver stage, my understanding reading Paul's description is that the grid bias is -6.4v, the plate current is 4mA, and the plate voltage is 185v. Plotting the load line yields an operating point near 135-140v at 1mA. Is this correct?
Another question that I have is how to interpret "the amp will have an input sensitivity of around 2.5vRMS for full power". Does this mean that the grid will swing 2.5v (e.g., from ~5.15v to ~7.65v)? I am guessing not...
