About simulations Kicad 9.0

[Oleg_V]

Hello friends!
I have been working with Kicad 9.0 for quite some time.
I am mainly interested in tube circuits (12AX7 and others)
I tried to figure out the simulation to apply, for example, a sine wave to the input and examine the simplest circuit.
But I can’t correctly connect the power supply, input signal generator and control (like an oscilloscope) to this circuit.
I understand that I am writing incomprehensibly for specialists).
Nevertheless. Can someone help with an example of the simplest circuit?

This would be my suggestion. Note the value of R1. You have 1 milliohm!

Don’t forget to find a model for ECC83 and store it in the symbol. My input source is wrong, sorry. Just use yours instead.

Simulation: Getting started with ngSpice and other resources

There are quite a lot sources and resources for getting started with ngSpice in KiCad, so I thought to make a list with links instead of repeating the information again and again and again and… Text Tutorials First, of course the ngSpice website itself. The link below is to how to use ngSpice with KiCad, but there is lots of other info over there, from the official ngSpice manual (ngSpice is a separate project then KiCad), to (links to) downloadable libraries with models. Videos If you prefer…

There is an updated (KiCad 9.0.4) project ECC83.7z available at Simulation examples for KiCad8/KiCad9/Eeschema/ngspice - #4 by holger .
