I got an Atari Hockey Pong PAL console that works fine, except that both left and right paddles SLIGHTLY like crawls up and down constantly, even when the controllers are untouched, so they never stand still. And yes, I cleaned the pots, and it made no difference, and I also tested to hook up a new and unused pot, but still no difference. I also replaced a 100uf cap, a 4.7uf cap, and also some cheramic disc caps nubered 68, 102 and 104, but still no difference. There are a few more mylar and ceramic caps on the board, but yeah not sure if this will make any difference replacing any more parts, and I don't have replacments for those at the moment. Hope someone here might know what's causing this problem!
