My arm is still tingling. I was connecting up the receiver/amplifier in my Tempest cabinet when my hand brushed the dangling monitor on/off switch. Silly me I had left the monitor plugged in. Well, it turns out that switch is line AC, not a sense DC. Now "120" AC isn't as bad as the 240 they use elsewhere (which can kill), but it'll still make you yell and jump.Current beauty shot of my Tempest MAME cabinet. Just added the speaker marquee this weekend.Still to do:1 - coin door: need a lock, mechs & switches, and connect it to the keyboard encoder.2 - rear door (espcially since it has live current exposed, lesson learned)3 - load & configure MAME, ROMS and FE4 - connect volcano LEDs to keyboard encoder
