This circuit is not much mine, I just adapted an existing circuit to use MQ products in a parafeed output. The pentode driver output impedance is very high relative to a more usual triode driver, being dominated by the 91K plate resistor. This makes it very susceptible to leakage capacitance in a grid choke, potentially limiting the high frequencies. Maybe Mike knows how much capacitance there is?
