Hi,
I will wind a shock coil for a class a se amp with a tube. What should be the technical specifications of this shock coil. Wire cross section number of turns.
7H 150ma

I believe you mean a choke coil (inductor). I’m not expert in coil winding but the answer involves your available iron core. In general:
To calculate the inductance of a coil on an iron core, use the formula: L = (μ₀ * μr * N² * A) / l; where L is the inductance in Henries, μ₀ is the permeability of free space (4π x 10^-7 H/m), μr is the relative permeability of the iron core, N is the number of turns on the coil, A is the cross-sectional area of the core, and l is the length of the core.

Hi Francois,
Thank you for all the information.
Is this enough information for you?

Sorry, I’m not expert enough to design such a choke from the basics at this point. Good luck with your learning, exploration and excution.
That video may be of interest:
The text book formula ( L = (μ₀ * μr * N² * A) / l ) is only valid for long cylindrical single layer coils.
