Here's the SPICE plot. The solid line is amplitude; dotted line is phase. It indicates a 1dB loss at 1kHz due to the 5K internal resistance I added into the generator. That did not otherwise materially affect the response.Note that the high end rolloff and phase shift will be greater than shown due to the input capacitance of the tube.
