Have you tried touching the volume control center connection with your meter lead or a hot soldering iron? You should get a loud buzz in the speaker when you touch one of those connectors if the audio amp section is working. Sounds like your output stage is working somewhat. Have you tested your tubes? A weak tube could send you in circles hunting for ghosts. I also know the 6A8 is a little odd, so you may not be oscillating. Might have to sub it to check, since it may check fine on the tube tester.
If I could find the place called "Somewhere", I could find "Anything"
