The early 30AX tubes suffered from a very short life. Mullard sorted the problem turning into one of the very best colour tubes of all time.
It's fat neck demanded high scanning currents but the focus was pin sharp.

I hope you can improve your 'grey scale' a bit but it appears your tube is near it's end. If you can get a replacement it takes only minutes to fit with just the grey scale to adjust. I hope you get it sorted. The K30 is an excellent receiver. John.
