This just reworks my circuit to use a controllable asymmetric current mirror instead of the FET for gain control. I take the

So this is the circuit I'm simulating in 24.1.0 with no component updates available.
I'm expecting it to take 2 hours to complete.

Thank you for your tip to wait 2 hours for results. For what it's worth,
Bill's original LTSpice source worked for me "as is."

Danke,
