I lack some of the models, and I'm running an old version, but after I  
made some substitutions, it didn't crash. Maybe the problem lies in one  
of those models.

Your two AC input pins have the same label, so the input is shorted.

Well... the immediate point is u1 is calling for "741" but you have the  
subckt called "UA741"

The names don't match!

LTspice did not crash for me. The SCH you posted had errors though.  

There are models missing for a couple of diodes.

I made a model file for the 741 and stuck it in .\Documents\LTspiceXVII\lib

If you provide the GV3S800 and 1N985 models, I might get around to trying those too.

Hello Robert,

This diode has a subcircuit-model, but the standard symbol of a diode  
provided by LTspice is for a ".model"-definition.

It's not a big deal to fix this problem.

Move the cursor over the body of the GV3S800-diode. Press the CTRL-key  
and right-mouse-click. A window with all the attributes will pop-up.
One line is
Prefix: D
Change the D to X
Prefix: X
OK

That's all. Now the simulation will run.

Background info: The reference designators of subcircuits used in a  
SPICE-netlist have to start with X whereas diodes have to start with D.

Best regards,
Helmut

   Thank you very much.

   That did not work as advertised.
   Best i could get was a pull-down filled with diode models.
   So, i modified the program and put .MODEL descriptions in for running.
   Well, the actual circuit oscillates and the simulation in effect latches.
   I also find that there is no .PRINT and no .PLOT; my DOS-based spice  
could put those fancy graphs on paper - and that was 25-30 years ago;  
what gives?

   Have added some part documentation and 2 .MODEL for the sim:
