Following mishandling, I have an electric resistance in burned into my rack SV32SR (Depth Range rack) my Neumann AM32, see the two pictures below:


This burned resistance has the effect of not having to pitch calculation in automatic mode (the needle on the poster is always right).
In "fix" mod, everything works correctly.
A member would he the electronic diagram of the rack? Or if a member knows the value and power of this resistance?
In advance, thank you all for your help.
