ok i got this amp i thought i ran into every problem i could. this pic is from the out put gate resistors. every time i put the output driver card in the red and green light comes on.

Which driver board are you referring to?

this is at the output gate.
volts/div .2
time/div 2

this came from a shop so im sure some stuff was replaced on it.

Are you sure that the scope was set to 0.2v/div?

If you set it to 0.5v/div and touch it to the B+ terminal of the power supply, does the trace go off of the top of the display?

Was there an input signal or not?

You can look at the solder joints and compare it to the other driver board to determine if anything has been replaced.

yes its set to 0.2 volts/div

If you set it to 0.5v/div and touch it to the B+ terminal of the power supply, does the trace go off of the top of the display? no doesnt move.

Was there an input signal or not? no

the resistors in the picture look like one end was taken up then resolderd to the to of the board.

Is the scope set to DC coupling?

no.

Unless you have a VERY good reason, ALWAYS leave it set to DC.

Try what I suggested again. What does the trace do.

yes the trace goes to the top now.
