Hello all.
I`m not good in Englisch, all so i make a Thread for all with this Problem.
My Oszi, very good, makes 1Sekunds Schschsch, then it goes even nothing.
No smoke because of default Parts. But it has smoked; between the High-Voltage-Circuit(green) and the Main-PCB-Board-Ground updown side!
See the Pictures at End. It`s a BG2000-641-505. I think it does not matter what kind of BG2000-641, because inside is all the same. The last 3 Numbers are only for Conection-Cabel. I by 2x Kaskade for 1 in stock. All so are the BJT: BUV26A, BC327 shortcut.
After changing the Parts all Funktion o.k.
Also i installed a 1A Fuse befor 230V Input.
