ok, i don't have much hope that someone will know the answer but just in case someone does, here goes.
Asteroids board that works except for a very low-level hum that's constantly present except when the saucers appear. at that time the hum goes away, which is kinda hard to hear because the saucers make a lot of noise. when the saucer is gone, the hum instantly reappears. this is easiest to hear when the ship is destroyed while the saucer is on-screen as the saucer stops shooting and is relatively quiet for a few moments until it disappears.
i took the board over to Dick Millikan's but it's nearly impossible to hear the hum on his test rig. i could just barely make it out (and did only because i knew what i was listening for) and he couldn't hear it at all. it's very obvious in the cabinet as having the speaker installed in an enclosure helps to amplify the low-end noise, including the hum.
very frustrating as it seems i have all the other issues with this cabinet solved and it otherwise plays great.
