What do you get when you touch the probes together, set on 200 ohms?
That meter is OK, for now, if it's in good working order.

OK. You should read the same (very nearly) from the non-bridging speaker terminals to the green arrow. Is that what you read?
yes. So I did it again to make sure im on the correct terminals and I am, it starts at 00.3 then finally drops to 00.1 and 00.0 but takes about 5-10 seconds
To clarify, when you stated that you lost audio, was it being lost at the output transistors?
These readings are OK. The previous 0.7... and 0.9... were not.

It never had audio, just powered on. The readings I was getting with my O-scope Im pretty sure were incorrect.
yea, it was connected to the emitter or third leg of the output fets while I was running an audio signal into the amp. When i pout the probe on the speaker outputs I seen the same signal, same wavelength and voltage. Thats why Im confused as to why there's no actual audio when hooking up a speaker. I guess I can try again and see if the same signal shows on the speaker itself, again maybe im reading something wrong but i have the probe set to AC at X10
So you did have audio.
When you connected a load to the speaker terminals, did that signal go flat?
Did the power supply shut down?

let me hook it back up and check that the amp was still on and if im getting signal at the speaker itself.
This O-scope has to be bad, this doesnt make any sense. When I probe the speaker itself I see the audio signal showing at 30v AC, thats not hooked up to the amp. Im going to try and calibrate it to see if that works.
yea, my DMM set to 20 AC shows nothing on the speaker terminals while the amp is on and I have a signal going to it.
With the multimeter connected across the speaker terminals then touching the speaker to the terminals, does the AC voltage on the meter change?
Try it at about 5-10v AC.
Try it at about 5-10v AC.
ok so set on 2v AC two of the channels give 0.10-20 and the other two are solid at .000 front left is .010, front right .000 rear left .000 and rear right 0.10
I don't quite understand. Why such low voltage? Your scope was showing a waveform of about 40v amplitude.
