Need a bit of technical advice, if potting toroidal transformers is a) not a bad thing and b) DIY feasable.
For the sake of looks and easier installation, I'd like to pot a couple of toroids. However I'm uncertain, if leads to problems with heat transfer (the transformer will likely be oversized by factor 2-4, due to availability). Also I'd like to hear about experiences with (acoustic) noise transfer.
If that checks out OK (like "there is no major downside) - how feasable is a no-further-equipment DIY approach? Sure, I'll need good potting stuff (likely some 2-component epoxy), non-conductive, certified for electrical appliances. Is that thin enough to reliably reach all gaps? Or is a vacuum chamber a must-have?
