Hi there,

Does anyone know if there is a reason why I cannot mount toroidal
transformers one on top of another (stacking them) with a single metal
mounting bolt going through both? I can't see anything on the web which
suggests I don't do this.

The magnetic flux from one transformer could interact with the other one
being that they are that close to eachother. *I've seen cases where cases
where the toroidal transformer was made up of two or more rings stacked one
on top of the other, and then the wire wrapped around them all.

I used to repair industrial electronics and I've never seen someone stack
toroidal transformers before. *They mount them side by side with clearance.

Consider placing a soft steel washer just larger in diameter than the
toroid between each.
