ahpook Posted January 6, 2008 Share Posted January 6, 2008 yup...accidentally plugged the wrong power supply nto it ans pffft...it's dead - big burnt track on the pcb. i think i'm cursed when it comes to amp simulators...my sansamp was taken out by a malfunctioning electric mistress... not sure i'm going to bother replacing it. /sigh/ Quote Link to comment Share on other sites More sharing options...
warwickhunt Posted January 6, 2008 Share Posted January 6, 2008 Just a quick ask but would any other manufacturers similar product had the same end result? I only ask as I've had a few Behringer products just die in a very short life span and for seemingly obvious things that wouldn't have killed other manufacturers stuff!

Hamster Posted January 7, 2008 Share Posted January 7, 2008 3V difference won't burn a pcb track out - that takes amps. What's the current draw of the pedal @ 9v - and what's the rated amps of the 12v supply you plugged into it? If it draws amps well in excess of it's requirements it's most likely a direct short.

The '9V' applies only at the rated current and will rise as the current drawn from the supply is reduced from the maximum rating. I guess you had the polarity correct - but any half decent designed piece of kit should be protected against that. As has been said sounds like a dud pedal just waiting to blow.

If the 12 volt power supply was wired the opposite to the 9 volt supply, that might draw enough current to fry a track. Quote Link to comment Share on other sites More sharing options...

I know what you mean though but no - any realistic polarity protection should work up to 100V or so minmum. It only has to be a simple diode at the minimum complexity. Having said that I had a diode fail in a mixer power supply once and the resultant noise was terrible to behold ( no - it wasn't a Behringer :-) Quote Link to comment Share on other sites More sharing options...

Count Bassy Posted June 10, 2008 Share Posted June 10, 2008 If the power supply was rated for 500mA at 12V then, if it was unregulated, the 'no load' voltage would likely be higher than 12V, as someone has already said. Also, if you put a dead short on it then the voltage would drop below 12V, but the current would go well above the 500mA. If the excess voltage caused one of the solid-state devices to go short, then the resulting current could easily cause a track to burn out. ie the track burning out is probably a symptom rather than the cause. Even if the supply was regulated then 12v is still 33% above 9V! What would you expect your telly to do if you connected it to 320Vac? Behringer stuff is cheap, so it's a bit unfair to expect it to be as tolerant as a Boss or something which costs a lot more, and we don't know how a boss would respond to a 33% overvoltage (dont try it!!).
