It’s hard to see but there appears to be a brown burn mark on my tube does that means it dead
Might be best if you can give us a slight indication of where to look. The only brown mark I can see is right near the little white circle of light reflecting (near the centre of the image). Is that where you are referring to?
edit: on closer inspection I can also see a brown ring-like mark down near the silver/metal thing at the bottom of the image.
@Yuusuf_Sallahuddin_Y yes I am trying to narrow down if it’s my tube or power supply that is blown
I think the brown ring is just a reflection but I will have to look closer
From previous posts, it’s usually either a crack in the glass or the end dislodges.
