My old 'scope blew up, smoke and flames.
Not wanting to connect my nicer 'scope to smps's running of the mains I've decided to fix the old dartronic, the transformer is toast, so I plan to rewind it.
Not a job for someone impatient, I've used a long knife blade and a teeny hammer to peel off all the E I laminations, took near 2 hours.
At first I thought the primary which I think is the one thats failed is on the very outer edge, but on closer inspection now the cores removed, it looks like 1/2 of it is on the outside and the other 1/2 is next to the core, and it looks also toasted, bummer, so I'll have to rewind the 'ole lot.
To make things worse I dont know the original o/p voltages, I'll have to go by turns.
