Hello
I am trying to build this circuit, and there are some issues i am facing.
I was able to make a working prototype on breadboard, but as i was getting happy and starting to make it permanent i thought i should check it again and then this thing happened. My transformer started giving strange noises and then cfl gone from bright to low and completely off and at the same time my transistor was burning damn hot. I had no idea why it happened? It was running great minutes ago and tested running it for 30 minutes and it was running fine and everything was cool, i have big heatsink installed on the transistor. Still when it was working during that 30 minutes, heatsink was safe to touch, but now it might even melt solder.
I tried different transistor, capacitor, resistor but the transistor is still getting hot.
Just to let to know, when i was packing it all up, i saw one of the high voltage wire was touching the heatsink of the transistor, do u think this has anything to do with this?
Also i used D313 transistor.
Regards!
