I bought a pair ot theese : Connexelectronic
and after putting them together I started them slowly raising the voltage to about +-4ov as in the manual (I have the 500w verision)and the red led lights (mute)at +-58v the green led commes on as it should and theres sound(music)but the middle IRFB4227 (Q4) gets quite hot,when raising the voltage to +-70v ,as it should work at it works for a while then the mute led comes on and theres +70v at the loudspeaker output.
I messaured the other IRFB4227 and its shortet..on both channels at the same time...I have e-mailed connexelectronic but not gotten a answer.Now,if I resolder the defect IRFB4227 and start the amp the outcome would be the same,right?But how do I find out where the fault is?
Is there a schema for this? I only got the manual from connexelectronic.
How do I continue??
