Re: Classical multivibrator fails in LTspice


They start, then wierdness sets in with oscillation dropping in and out, that sort of thing.

In my experience, this is often due to letting the simulator choose the integration step, especially if there are hard nonlinearities. Limit the time step to 1/100th of your signal period and you should get better (i.e. sometimes very different) results.
