Recently bought a K40 and once it had been delivered I started the allignment proces, which went good. I hit almost dead centre in all positions (after tweaking), at the end of the proces I started to notice that instead of 1 burnmark i got 2. Traced it all the way down to the tube, so the tube produces 2 dots…
Also when firing the tube, the beam seems to arc towards to anode at the end of tube, I made a video of this, is this normal? Are the 2 problems related at all?

Your help is highly appreciated!
I run (cooled) distilled water between 14 and 17 degrees celcius (which is optimal, with my knowledge)
