I would recommend watching this:

I see a lot of wires and components with no mechanical connections and a lot of solder joints that aren't likely to work well. It's quite possible that remedying these issues will leave you with a working amp.

Yes, I'm sure the LEDs don't light up. Please don't focus on them though, that is directly related to the soldering issues.
Well, I watched the video (very helpful!), took a pass through the joints and tried to re-do things best I could.
Unfortunately, so far it has not made any difference - getting same voltages.
Resistance checks fine, tubes glow, but still no LED and same bad voltages
Attaching new picture.
Any other thoughts or suggestions would be appreciated!

Can you very carefully take a DC voltage measurement at A3?
That is typical for an open LED. I would order up some replacements and use a bit less heat when soldering them.
(There is also the possibility that the jumper between upper and lower levels on the volume pot where the black wires connect is missing, so double check this as well)
