I have a kickman with a G07. The colors are kind of "washed". I'm gonna try to adjust it, but if that doesn't work, is there anything that could be replaced to bring the colors back. I assume its in the tube though.
Have you done a cap kit? That is always the best place to start and will correct a lot of issues. If you have a rejuvenator that will let you know if the tube or the guns are weak.
A cap kit can help with color issues as well as a variety of other symptoms. It is not a one-stop shop for all problems but it is the most common culprit before investigating anything else. Good caps set a baseline for troubleshooting...
I have a Sencore CR-7000 if you feel like driving to Pittsburgh. lol I would try the cap kit especially if you don't have a tube tester or know someone who does. I'm sure you can send the kit and chassis to one of us to do it for you. By the way. I wouldn't learn soldering on a board you need. I found out the hard way... Pick up any pcb from an old tv out for trash or something.
