Having attended an LTspice seminar yesterday in Arizona, and lunching with Mike Engelhardt (*), I learned a number of tricks...
Main trick I learned is that it is trivial to make auto-generated symbols... so I will be gradually updating my Device Models & Subcircuits Page to include LTspice symbols (.asy) 8-)
(Roughly 1/3 are done today... be aware that you will have to adjust model calls to fit your particular library path structures.)
(*) He caught me by surprise, asking, "You designed the MC1648?" He used it with a self-machined helical resonator to make a very high spectral-purity oscillator. ...Jim Thompson

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

I need to simulate an analog circuit but I could not find any orcad pspice model for MC1648. Do you happen to have any? It would be a big help if you can share it here.

I designed the MC1648 before there was a Spice program (mid 1960's). The only thing I can find that might be useful to you is the following LTspice schematic file... which I suspect was ginned up by Mike Engelhardt himself:

It's what you learn, after you know it all, that counts.
