Brand new here so I apologize if this is the wrong place or if this is just a plain stupid question. I'm building an isolation transformer out of a couple transformers that I got from old stereo receivers (these things are amazing for build components. Pots, switches, jacks, MOSFETs, relatively large transformers - these 2 also happened to not alternate E and I sheets, so I can easily break em apart, large heatsinks, large capacitors, and more). They're nearly identical (same manufacturer, same dimensions, nearly the same color wires even) so I decided they'd make good candidates for an isolation transformer. Unlike MOTs, these have the secondaries wound around the outside of the primaries rather than being stacked. So my first thought was to just tear off the secondaries and I sections of the cores and then attaching both E sections together with the mains primary coils making it an EE core transformer with identical primary and secondary coils of mains voltage. Which to my understanding is exactly what I want for an isolation transformer. While planning it out, I was considering how I could add in cooling fans and thought that would be simple if I could keep the secondaries, meaning it would be a 4 coil transformer. Now, I've heard of these existing, so I know the concept isn't impossible. But is it wise? I've not been dabbling in this field for very long (the "field" I'm referring to is "building custom electrical devices", which is probably evidenced by the fact that I don't have an isolation transformer already). I've been really getting into it for just shy of a year now and collected a good bit of components from devices people were throwing out/giving away/or I found super cheap. This isolation transformer build is using all parts that I've accumulated except for the enclosure that I am likely going to print on my 3d printer.
Any and all guidance would be greatly appreciated. And just let me know if you need any other details/pictures, etc. Thank you ahead of time.
