I love to cook with wine. Sometimes I even put it in the food.

The thread "$16 minimum wage for burger servers?" is more entertaining,
but thanks anyway.

I have re-posted the TDA2003 subcircuit, eliminating one of the LIMIT
(*) functions that I suspect is causing LTspice to lock-up on John
Woodgate's current-drive amplifier...

http://www.analog-innovations.com/TDA2003.zip

replacing that function with my smoother TANH approach.

Let me know how that plays.

If there's still an issue within LTspice, I'll rework the SLEW LIMIT
as well.

(*) The use of LIMIT dates back to when I didn't know any better :-[
.... all my recent models use TANH for any bounding needs. (LIMIT
works in PSpice, but I've grown to distrust it.)

Yep. One of the reasons why I never bothered to implement the if-else
construct that the uninitiated put into PSpice, and was copied over to
LTSpice, in SS.

Discontinuous functions and discontinuous derivative functions are an
accident waiting to happen.

Yep. The surprise was that LIMIT works in PSpice effortlessly without
any OP convergence issues, but throws LTspice into fits where it gives
up.

However, I _do_ use IF/THEN/ELSE to set parameters that don't change
during a simulation run.
