hi guys
i dont want to fry my Trends up, a rather basic question, but would rather ask and look silly, than make a big mistake.
I have bought some croc clips, , a DC plug, and got some wire so i can affix a battery to my trends. Im just wondering if the Trends is negative grounded, does that mean i solder to the outer metal sheath, and positive to the inner metal pin. And if its positive grounded, its vice versa?
just making certain thanks for any info. |

Tried to delete this post, as its like ritual humiliation, ha ha ha, but where as you Hobbyists (obsessives) cough, started messing with electronics when you were in nappies, i didnt pick up a soldering iron till last year.
(mistaken for a hot screwdriver)
:clown:
Anyway, once again ive learnt something new, and not obliterated my amp yet, we can but hope:D |

| Look on the power supply and there should be a nice picture. Pos center, Neg outer. Looks like you got it right. |

Strange.... I thought I replied to this thread last night - and that the content was a bit different. I was feverish and dizzy last week, but feel fine this week. Or maybe not. :cannotbe:
Oh well. Good to see that you got it sorted.
Center is Positive. Don't reverse it or you will kill the chip. Enjoy the music! |

| I reversed mine very briefly and it didn't kill the chip. It didn't boot up the first time, and I was right to assume I got the leads wrong. After switching it, it turned on just fine. I guess I got really lucky, or Trends buit in some protection at some point. |

It was after reading David Kans review on 6 moons that i read about his accident that burned the chip out. Also in the beginning when looking at the diagram, and not using any common sense i decided that it was positive ground. Only after closer inspection of a diagram online, as i wanted to check it, did i find it was negative ground. Nearlly, nearlly soldered it the wrong way round.
Im getting the Tank caps, and Auricap, input caps, + heatsink soon, that should add more fun. All thanks to Panos mods.:D |

emperor. You can get a fantastically indispensable gadget from Maplin for 99p which tells you which way a power supply with a 2.1 or 2.5 mm plug is wired. It has 2 LED's one lights up if the centre is + or the other if it is -. Best thing I ever bought for 99p!
Oh nearly forgot, both light up if the current is AC not DC. Brilliant. |
