AC-30 Sim

[changes]

Hey Elektrojänis
pretty cool thanks a lot really

[MarkB]

Did anyone ever figure out who (if anyone) Stephan sold the design to?

I think some people suspected that it was that 'v-stack' .. but has anyone confirmed?

I am offended on behalf of stephan.moeller!

I've been working on this AC30 Tube Simulator project for some time, and published the results on my blog. I obtained values by comparing LTSpice simulations of the original AC30 valve circuits and the Stephan Möller circuit. I started by giving credit to his excellent work.
These are the LTSpice simulations:
Tube Simulator - Simulations - Preamp (1/3)
Tube Simulator - Simulations - End stage amplifier (2/3)
I modified the Speaker simulation circuit using Sallen-Key filters:
Tube Simulator - Simulations - Speaker simulator (3/3)

These are the practical implementation posts:
Tube Simulator - Practical implementation - Schematics, BoM (1/4)
Tube Simulator - Practical Implementation - PCB layout, manufacturing, assembly (2/4)
Tube Simulator - Practical Implementation - Chassis, face plate (3/4)
Tube Simulator - Practical implementation - Test, debugging and verification (4/4)

And this is the sound check and comparative with some AC30 emulators:
