Memphis 5 channel amp

[caraudioguy2100]

Not sure of the model number of this amp since no where on the sink is the model .

anyway amp powers up but will not produce the positive regulated voltage .

any ideas where to check?

yes I know the positive regulator is out of the amp right now I removed it and do not get any voltage on all 3 pads for the regulator

Small green inductors?

 

[caraudioguy2100]

They all test fine

 

[caraudioguy2100]

Sorry missed 2 of them one is bad will replace and post back

 

[caraudioguy2100]

Do you know why these inductors would go bad ?

 

[Perry Babin]

Is the failed inductor failing again?

 

[caraudioguy2100]

No the amp works now was just wondering what causes them to go bad

 

[Perry Babin]

They rarely fail randomly (from what I've seen) so their failure is often do the the failure of something else in the circuit with them.

What else failed in this amp? Or was it only the inductor and nothing else?

 

[caraudioguy2100]

Only the inductor failed everything Else in the circuit tested good and the amp works has been playing for 30 mins now

It could be that its current capacity is pushed to the limits in this amp, random failure...
