I finished my Stereomour yesterday and after the reading looked good hooked it up my Orcas and turned it on .Nada! Got to be the Dac or the Mac Sound setting or SOMETHING not connected to my build. After hours and trying to find the problem I went ti bed and in the morning pulled the tubes and put it on the bench. Oh, Oh,My. I never did the after completion connection check, just resistance and voltage, because I know just how careful I am doing a build and all my connections are Perfect! In the first half hour I found 3 Unsoldered and three very maybe's. I was so shocked at my poor work that I just quit for the night...disgusted. You may be a lot better then me, but then again, who knows.
This may or may not get this rig running but Ive learned a new tool for my craft.
