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...

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.)
