You must post pictures. At the very least exteriors but you will earn bonus points for interior pron.
Anything less is unacceptable :-- :-DD

Rest assured if successful, there will be pictures, of both the exterior and the internals, can't live without some porn in my life 🤣

Once it was a major human health hazard.
It makes my skin crawl just to see someone let their dog lick their face and those that insist walking their dogs on school playing grounds. :scared:
YUK !

Au contraire - a little parasitic worm exposure can be good for you. Without it you’re more susceptible to a bunch of really nasty autoimmune diseases. Some tapeworms with your TEA mon ami! >:D

I'll contribute some ugly teaser pron. :palm:
This is an isolation transformer I built from scratch almost 40 years ago. Back in the day when most TV's and all radios were not fully isolated from the AC line and one of these units was mandatory to safely work on them.
Interior view. 2 salvaged transformers in parallel to get at least 120 volts. Yes, it's ugly in there but it's fully grounded and I consider it safe. If I were to build it today I'd used much better construction techniques.

Hmm, interesting, not quite sure how you mean that having two transformers in parallel provides 120V, surely you'd get that from a single transformer.
I like the idea of the voltage selector switch but out of interest, what is current ratings of those wafer switches?
The front looks nice and neat and a nice touch with the load switch as well as the incoming switch.

Oops, I meant to say series. My bad. One transformer was salvaged from an audio amp that provided 102 VAC secondary. The other transformer has multiple low voltage taps on the secondary. Series them together to get 120 volts or close. If I recall correctly the wafer switch was rated at 3 amps but don't hold me to it. I never had any problems with it.
