Is the channel distorted, or have any DC on it?

Is your scope out of focus?

No DC, not out of focus. That's the way it looks. The other channel is fine

Is the sound distorted when hooked to a speaker or does the signal change when hooked to a load?

Its the same as the Power 250.2 I know I have it, its a matter of finding which hard drive its on. I will look now and let you know.

Do you have the x-over cards in full range?

Have you confirmed the bass and treble pots are ok?

Does the channel bias?

I have placed the xover cards every which way and no change.

No bass and treble pots on this amp.

I have not checked the bias, will do that in the morning.

Oh yes I forgot this does not have bass and treble pots. Do any of the switches ie: balanced/unbalance or the 0/180 or the 0/180/ez bridge have any DC on the casing?

There is a 0/180 switch for each channel and one of them is 0/180/ez bridge.

Sometimes these switches being bad can cause strange issues.

I am looking for the schematic now.
