Piling two toroidal transformers
Hello guys,

I am going to build a Gainclone amplifier, and I am going dual mono inside the same case. The question comes to how to alocate the trafos.

Is there any drawback in mounting one above the other using a single bolt? I've seen doing it, but I dont know if they will interact with each other.
Doing that, there is enough clearance to fit a 3rd trafo for supplying another pair of Gainclones, making it a 4-channel amp.

I forgot to say that, being a 3U chassis (12cm height), it is possible to put a 4cm piece of something between them, making a sandwich. Maybe rubber or something i can find. They will share the same long bolt.

Thanks for all,

Take a look at this post from yesterday, it might answer your question

Thanks for your response. I have been researching the web and seems to be feasible to stack them, but better to separate them as much as you can, using spacers between them.

But I still want to hear any other experiences or theorical explanations :p

if they vibrate at all on their own they will vibrate like hell on top of each other. Usual practice with stacked transformers is to pot the bottom with a long bolt and mount the top one compliantly.
