Yup my bad, forgot about the MOV. My computer PSU has one of those too, so i don't think it would help greatly. I still wanna get a full-blown UPS.
Anyway, finally good news. I've gotten my old computer back in one piece again, it's a machine i built for fun a few years ago to see just what i can do with it, and mind you, i did a lot.
What Core 2 Duo? What 8GB RAM?? Here goes the oldschool.
Asus P55T2P4 mobo
Pentium-MMX 200MHz overclocked to 292MHz, running at 3.5v core and kept below burning temperature by means of a large Athlon cooler
96MB SIMM memory running WAY faster than it was supposed to
2MB ATi video card
13GB Seagate HDDThe almighty Sound Blaster 16 ISA
3Com Etherlink III 10mbit network, yup, ISA as well
Ever seen a ~300MHz Pentium 1? Me neither. Mine could very well be the only one in the world.
This thing is 3x faster than the Dell P4s we have at school, i'm serious. Yes my HDD sounds like farting, and yes it's got one of the crappiest keyboards in the world, but it runs well. It's even got USB!
I have installed Windows 2000 Pro and have gotten AudioTester to run. With rather high latency, but the results are good. Now for the ground-breaking news.
I knew i wasn't gonna break the SB16, as it's the largest soundcard i've ever seen, no way a bit of AC is gonna hurt it. But i played it safe and tested the cables for voltage before i connected the speaker.
All fine, except one thing. With one probe of the meter on the tip of the RCA that was supposed to go into line in, and the other in my hand, the voltage jumped over 12v AC. I realized that i was sitting with one foot on the carpet and the other one on the floor - i moved both my feet on the floor and it dropped to ~2v. I carefully connected the cables as not to touch them, and was able to measure both that damn midrange and another 12" woofer without any hitches.So there you have it, the source of the issue was me.
I do remember touching the wiring when i blew my PC onboard, as i was pulling at the wires testing for bad solder. Now, why the heck did i have a 12v potential above the amp's output cable, that's a different matter. I think the interference could have something to do with it.
Thanks for appreciating my English - when i was 5 my father went to the UK, and he brought me lots of English books and tapes to learn from, and he'd stay with me and teach me English twice a week. That's how i know it so well.
