It is not a problem that I suffer as such and I like when it happens, I know that Williams shares the same sounds in many of his machines, What seems curious to me is because in the firepower II that I have, it happens that it makes sounds from other machines, for example: The Target of the eject Hole when hit makes the effect of the blackout background sound, That this happens is not annoying, but I want to know why it happens and what happens in the system, I know that it is not bad but as I said it seems curious when it happens, It becomes more common for the sounds of the other machines to appear if I leave the machine off for a long time, like one or two weeks, I hope this is not an error and if it is, it is still not annoying.
And can you recommend a page that sells LEDs for this machine?

It is already solved, I only ask two things, because it happens and if someone knows where I can buy LEDS for pinball, as I said it is not annoying, it is just curious
