stacking transfomers

Due to size constraints i cant fit a large enough transformer in my case. However i can fit 2 smaller transformers in the case to get the needed va. Would it be a problem to parallel 2 transformers and stack them either side my side or on top of each other for a single voltage source?

Stacking them one on top of the other is fine, just be sure to use metal standoffs and consider mating the standoffs with both the top and bottom surfaces of whatever enclosure you are using. What type of transformers are these? There maybe be some rare cases where such stacking isn't optimal.

That's fine. Personally, if I had two transformers, I'd build a dual mono amp.

If these are toroids, do not connect both the top and bottom of the mounting bolt as this will result in a shorted turn. The transformers will get hot and will not be happy

Ive heard never use steal screws to begin with. Anyway they are toroids. I wanted to make sure that running in parallel was ok and wouldnt cause them to heat each other like the power line transformers do.

Ps they will be identical. Same vac and voltage, and load.
