Piling two toroidal transformers

[regiregi22]

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.

Thanks,
Regi

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,
Regi

Take a look at this post from yesterday, it might answer your question Dual Toroids in Close Proximity...An Issue?

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

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.
