Hi John, I want to analyze just one signal point in 27 variations. Just to understand which influence have my 3 potentiometer in 3 different positions. Helmut's way works great. Even if I only have 4

Thanks Helmut, works great. Sven

Hello, Copy the file LM6172.MOD into the folder of your schematic. Place an opamp2 from [Opamps] in your schematic. Change the text opamp2 to LM6172/NS . Include the model file with the

Hello Sven, 1. Attach a cursor to e.g. V(out). 2. Use the up/down arrow key of he keyboard to jump to the waveform you are interested. 3. Move the mouse cursor near the waveform-crosshair. The mouse

I am new to LT spice. I want to use the component LM 6172 in my schematic, I have downloaded the include file from the the path and used a generic opamp2.asy. However, the attributed is same as

Hi there, I am new here and have a newbie question. The .ac analysis of my tube schematic shows 27 graphs as I run 3 potentiometer with a step directive: .step param a list .1 .5 .99 .step param b

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

Out of morbid curiosity, I opened the "transPPb.INC" model file, and noticed a gross error. The description says total primary L=100 and the individual inductances of both half-primaries is spec'd at

Guilty, what can I say, but I really can't escape the feeling there was a topic somewhere about some impossibility of having two primaries in a transformer. Maybe there are some crossed neurons

I believe you see why I prefer the multiple winding solution. Having to open the model with a text editor and reloading it in the .asc file is not my idea of immediacy.

The problem with multiple primaries is that it may create conflictss if two sources are too strongly coupled. Indeed, when using multiple primaries, one must make sure the voltages, phases and source

I'll add another vote. I've used LT Spice daily for many years now... The book is excellent even for people reasonably skilled in the art. The sections dealing with magnetics simulations are

in the Fender schemo. Using the "Fender Twin Reverb" example, the output transformer is modeled in the model file "transPPb.INC". Any text editor should do. I also see extra nodes/elements for

Well, I just tried it and you're right, it does work, but I know there was a discussion some time ago (years, probably) about not being able to make a more than one primary transformer in LTspice.
