Lock horizontal axis
(1) Choose any plot, drag a rectangle over it all, then all plots get same time axis limits. (2) Doing this with "Manual Limits" only zooms the plot selected (not all). So: What I'd like to be able to

Re: Pull-Push transformer for valve amp in LTspice
Hello analogspiceman I'm not denying that your library works (I have used it a few times, successfully) or that a quasi-real transformer can not be built around the Chan core, but I have never used it

Re: Pull-Push transformer for valve amp in LTspice
Hello Vlad, a transformer has multiple windings, but only one core (which is the only nonlinear part). That is why LTspice does not allow coupling between saturating inductors (either Chan or

Kevin replied: ? "? PULSE(-6 6 0 5m 5m 1p 10m)" That is how I'd do it too. Except that I probably would have used 0 rather than 1ps, because the on-time Ton is allowed to be zero. The waveform is

Re: Graph Color
Hello Sven, After you have decided which plot(s) is the best, you can plot only one or a few of them using the @ selector. V(out)@12 V(out)@23 Best regards, Helmut

Re: Pull-Push transformer for valve amp in LTspice
No, it wasn't about basic usage such as this, I think it was about analogspiceman's "xfrmr" library, two primaries for a push-pull or similar, some year or two ago. I tried to search the archives but
