Ashhar and all,
I found the problem and fixed it. It was not completely bad soldering on the DC connector, it was also the 1N4148 diode in series with the incoming 9 volts being OPEN. After re-flowing all the solder joints from the component side and checking continuity, I still got nothing from the 9V connectors + side to the side terminal on the main DC connector. I checked continuity from the cathode of the diode to that point and it was good so I checked the diode -- no forward conductivity at all. I have a well stocked parts bin, replaced the diode and now everything works as it should.
Anyone having this problem that re-flowing solder on the DC connector doesn't fix, be sure to check the diode as well. 1N4148's are pretty rugged but I've received bad ones even from Digi-Key and Mouser in the anti-static strips they come in and it's not all that uncommon.

Oh yes, how about a written manual in PDF format rather than video? Some of us would much rather read the book rather that watch you-tube videos. Especially when needing info and the internet is not available!
