Hope you will help me.
The simple answer to your question is this:
- Draw it in LTspice.
- Press RUN.
LTspice is quite capable of simulating electronic circuits such as this. It is one of the most capable simulators for that. Why go to another tool when you have one of the best in front of you?
That being said, your next step is getting good or good-enough SPICE models for all the parts. R's, C's, and most L's are not a problem. Semiconductors, maybe no problem either, but people come up with obscure transistors and then expect someone else to make them a model. Often a model borrowed from another part is good enough.
Pots can be simulated as two resistors in series, as everyone knows that is what they are.
And then there are the transformers and relays.
Linear transformers (where the core has no hysteresis and does not saturate) are simple to make in SPICE but you need to find the inductances, turns ratio, and DC resistance, and often nobody knows what they are, so that is part of your job. If you have a schematic such as this which has no clues on it, then your work is cut out for you.
Relays? Do you really need to simulate them? You must understand why. And then you can come up with a basic model that works well enough.
Now let's start with a few other matters:
- Never upload a .RAR file like you did. Did you bother to read the group's guidelines? Go there and do that now. (I fixed your file by changing it to a .ZIP for you. Next time, do that yourself before uploading.)
- ZIP files are definitely suitable. Did you bother to read the group's guidelines? Go there and do that now.
- Photos go into Photos, not Files. Do not upload photos into the Files section. Did you bother to read the group's guidelines? Go there and do that now.
- I recommend not uploading .webp photos. Some graphics programs have trouble with them.
- Is your schematic dependable and accurate? It says "Autotransformer" but that is not an autotransformer. The circuit around the LM324 looks questionable, but I did not draw it out so that is a snap judgment. Did the person who made that schematic know what they were doing? I question whether they did. You could be wasting your time trying to simulate a bad circuit.
