I used a master/slave powerstrip, so when the computer shutsdown everything else loses power. Likewise when the computer starts up, power is restored again to the marquee lights, screen, and audio amplifier. However, each time the speakers will emit a very load 'bang'. Besides being annoying I have no idea if that could damage the speakers or amp. Does anyone know what might cause this? For now I just switch off/on the amp manually as its reachable via one the of the coin doors. |

My computer audio speakers do the same thing and I hadn't bothered to figure out why since I rarely turn them off. As far as I can tell it's an energy surge that makes them pop. Here's how one person explained it and gives hints to resolve. When you switch off the power to your amplifier, its power supply will collapse asymmetrically which will cause the amplifier’s output to be at an indeterminate state when it should remain at zero DC. This results in the switch On or Off thump. Most amplifiers will contain an output relay to negate this problem - the relay is energized or de-energized only when the amplifier’s output is stable. Here's a car audio post that looks like it covers both off and on pop issues with ways to mitigate. Given a lot of this hobby seems to either use PC speakers or car audio amps and speakers i would hope this solves it. Very interested to hear if this works for you https://caraudioadvice.com/how-to-fix-amp-speaker-turn-on-turn-off-pop/ |

Wow, thanks a lot for the link. Seems I have some testing to do, in order to find out the actual issue. |

I always come back to look at builds with the rotated displays to get more 4:3 real estate. Nice job! I like everything about this cab at the same time I'm wondering if the depth of the cab was primarily to fit the display. It's actually pretty loyal to the original in terms of how deep CRT cabs were...so was the depth used to mimic the original or to fit the slanted angle of the LCD? |
