How can I set the G2 screens my 6PG / GE601? I have a scope, multimeter, video essentials DVD (PC DVD set up) and 6PG service manual. But as far as I can see I would need a colourimeter to do a complete set up (though I have a post on using silicon cell instead), and the overall procedure seems horrendously involved. All I want to do is set / check the G2 screen setting to make sure I have the max sharpness without cathode wear. As far as I know all other relevant pots are as factory set. TIA. Clive.
