Hi, I've got a problem with lower playfield ball eject. The ball release solenoid works but the hole out kicker solenoid only shoots the ball about half way up the tube. I replaced the solenoid with a A16570 because the old one was fried. I also replaced the 2n6879 transistor. Do I have the right coil, or should I look at something else. Everything else works on the machine except for the sound. I don't think the sound board would cause this problem. Thanks.

Good news , I have it working now. problem was someone had the wrong coil in it. I put the correct coil and now it is working. Still have to go after the sound problem. Thanks all!
