Hey everyone. I have a K7000 that I just capped to try and fix a problem. It made no difference. I have a 'wavy' horizontal top edge of the monitor. If I install this same chassis and tube in my MK2, it's fine. The problem only happens in the MK1. The horizontal hold pot just moves the 'waviness' around, but does not fix it. See pics for details. Any ideas? Much appreciated - Mike.
