If you have 10k and normal brightness then everything is fine. The HV will vary a little depending on brightness but as long as it doesn't sag below spec then it's good.
Low high voltage will reduce the brightness but it will also cause the picture to bloom or expand as the brightness is advanced.

I'm guessing he probably meant voltage, but it is common to hear voltage referred to as current for some reason. Either way, where there is voltage in a completed circuit there is current (amperes), but I have never seen a spec. of any kind in relation to HV on a cathode ray tube. We know that current (I) is found by dividing voltage (E) by resistance (R), OR by dividing watts (P) by voltage (E), just to name a couple of formulas. I'm just not sure what variables you would plug in to find "current" of CRT HV.
