Jeff, I can get 90% of the bows out of it by adjustments. I have checked my cable connections twice. I have tested the 110K, and the 82 K resistors twice. These resistors have to be OK, cause my +16 volts is OK. The ring magnets are OK, they were sealed with silicone, and havn't been disturbed. I think all the adjustment pots must have been messed up by someone else, cause the customer bought it used, from someone. I am going to review the complete convergence proceedure, and start from scratch again. I still think I can swing it in, just need to spend more time on it. Thanks, LLW LeRoy Westlund Westlund TV & Electronics 97 North Main "Where there's a will,... Centerfield, UT 84622-0087 There's always a way."
