Hi,
I'd like to share a recent experience. I've been looking at low cost power supply solutions for pre- and headphone amps, and after a bathroom refurbishment at home I noticed a very nice isolation transformer in the shaver socket. I quickly bought two second hand on ebay for £5, and was pleasantly surprised to find a 20VA transformer with a tapped secondary. Tried both full wave and bridge, with load currents in excess of 50mA DC. Full secondary DCR is 140 ohms. Add a small smps for heaters and there is a low cost solution. Not for everyone, but may be of interest for some.

That isolation between windings is nice! Would allow you to be able to fall asleep...I assume the plastic on the inside of the windings is likewise.
i'm not able to find anything off of the numbers on the transformer itself, mind sharing the model number or search description?
All I have is the picture in #1, showing the label. I measured myself the DCRs, voltages etc. The labels shows "Legrand" brand, but I would be surprised if they were the transformer manufacturer. I doubt you will find those transformers sold separately.
Edit: I may have spoken too soon...

I do not see it there though.
