my germany made Ansmann travel adapter decided that 12V isn't enough and gave 30V to the board.
and in the process burned 2 of my boards. cry.gif

it's branded for god's sake. wtf

paskal,
Your travel adapter 'decides' 30V? How come? A converter you mean?

Kesian... you know what to do with 'disobedient' adapter, right? tongue.gif laugh.gif
So, you got your T-Amp running proper, now?

before this, yes. i got one board under extensive mod process so that one can't be use currently. and that one is the only working chip i've got with me right now.
so now i don't have any working setup. it burned 2 of my boards demmit. that adapter is now history.

any of you guys would be kind enough to get me one of those Meanwell and ship it to me? would be much appreciated..

paskal, how badly burnt is it?

Pardon my lack of electronics knowhow...but I see this smd capacitor C5 in the 12v+ circuit leading to the TA2022 ic. Wouldn't this burn out first?
*

it's not burned or anything. doesn't even heat up or end up in smokes. the chip and circuit looks absolutely fine without any burn marks.

the only thing is, the chips are now shorted to ground. the input have a connection to B+ and GND. rclxub.gif both boards exhibit the same simptom. considered dead.
