Hello everyone,
I'm new here.
I've been watching daves blogs for some time now and I've seen a lot of youtube movies about osciloscopes.
So as adviced in the videoblogs I went looking for an old analog osciloscope and I found this philips pm3055 on the internet.
The seller told me it was fully working and when I received it, I plugged it in and it seemed to be working fine.
However a few days later I wanted to play some more with it and it was still working at first. But after some time it started to release smoke and made the sound of a short circuit somewhere inside.

I decided to open the housing and I pulled out the board with the power supply. The most obvious thing I could see was a blown capacitor and I also found some 3kV ceramic capacitor leading to the crt that seem to blackened. I attached some pictures.
I would like to know if this demage can have come from something I did or I just bought something that was on the edge of breaking down anyway..

I would like to know if you think I would be able to repair this or not.
