Majestic Buzz working now!

[ForthMonkey]

I've just built Majestic Buzz summing mixer.Used NE5532.Not used non-polar 220uf caps.No out trafo.I can't get any signal from output.

Everything looks good.PSU is ok.

When i touch input i can hear noise but when i send signal,can't hear anything.

What is wrong?Do you have any idea,masters?

Thanks.

Second try and getting big hum but sometimes!  ???

And i have strange issue.

When i plug mixer to main AC,getting high level hum.But if i change pins of main AC(reverse),getting low level hum.Firt time i'm getting error like this.

But still no signal.

Now it's working but there is strange thing!

When i get signal from hot wire,getting really low signal.But if i get signal from ground,it's working good.

What is strange issue about main AC? When i change pins,hum goes away.About transformer?Regulators?

But i'm getting +/-15 volt with no issue.

First of all,i understand that output transformers must be used on this design.Now getting signal but as passive summing mixer with low level because of resistors on the way.

Active part not working.Only getting hum when i plug into AC.

Now it's working with no issue!No humming!

Just connected ground to output xlr pin1 and working great!

It's fully working.Now waiting for case and trafos.

Here is what i have for now.
