Is it completely insane to try an AC701K in a U67 with appropriate power supply? I haven't found an example of anyone trying it, only endless commentary about the sonic differences (or not) between the two models.
At a glance the circuit differences appear to do with variable pattern, or not, unless you're talking about the M269C cathode bias version. One resistor value difference in the calibration input.
AC701K in a socket adapter, correct PSU voltages? Why not? Curious. Someone must've done it.
