Yes, they are. The two ferrite chokes on the EI40 cores with an air gap of 3 mm in series do not heat up.

They were transformers from PC 400W power supplies. EI40 cores and an air gap of 3 mm is added between E and I. The entire secondary winding is connected (original branch 12V) The primary windings are not connected. Two transformers are in series.
My Questio:
"Are the output series inductors two halves of a common-mode choke"
referred to the amp schematic you showed on #21 and not to the power supply

These are two separate identical chokes connected in series.
It used to be PC transformers and an air gap of 3 mm is added.
4x Toroidal coils are in the power branches for Mosfets.
4x EI40 are output coils.
thanks, this could work.The power supply consists of old modified PC power supplies, each containing two transformers.
