Clacking bell!
I was minding my own business, measuring DIY spotwelder controller with a transformer and doublecheccked each time all is fine....Then it got time to measure thyristor and ofcourse I checcked that scope body was "zero" and same "zero" that line that feeds the thyristors.
I put the shuko on

Yup this outlet could go either way...I though I did not fiddle with it. Wife noticed that fuse blew, because outlet from that bedroom went off too. I was affraid that that I fried the scope, but noooooo.....Just good oldfachioned scope "ground" to phase error

OK. This scope is nowwhere as good as these beauties, but maybe it's easier to float.
Pretty german Phillips (Two tubes, othervice transistors) does not sync. I got one nearly as old UK made one and that mostrly works...
Where you get 1:1 and 1:10 scope probes?
