Do you have a rail to rail square wave on the output transistors. If it has only one rail, 0v to rail square wave.

On the next 4 outputs per side i get the following squarewave on the middle leg--- pic 2 Scope settings--- 20 volts div 2us The 3rd pic is the gate legs of the outputs that have a squarewave on the middle leg Last edited by mike49504; 15th March 2012 at 10:05 PM. |

You stated that he stated that it had very low output. Does it produce only low level audio out when driven with a strong signal?

When he brought it to me he said that it had low output .. On the bench i can only get it so loud but it seems to be working correctly for me..
He also stated that a kicker 1000 watt amp was louder in his car then this amp.. So not really sure if theres anything wrong with it or not just going by what he said.. |
