Are ITs useable in the single ended Pentode amplifier? I have only seen them used when the final tube was a triode. Does the Pentode have the wrong impedance, or some other objection for transformer coupling to the drive stage?
Perhaps pentodes came on the market at the same time as ITs were going out, so IT coupling was not done with pentodes back then and is therefore not traditional, so nobody does it today.
Anybody know?
