Well done, your 12AU7 is now operating properly, both LED's must be lit at this point.
Now, the 6080 is being presented with a reasonable operating parameter, but it it sucking current like crazy!
Can you check that the 3K resistors are in fact 3.0K?
Next, triple check that the 100uF/160V caps are connected properly (striped sides out), and that the wires running to the headphone jack leave the outboard terminals (6 and 10) on the terminal strip? If those wires were connected to 7/9, you would experience these issues (until the 2.49K resistors cooked).
Let me know if these suggestions are helpful, and especially if they are not.
