Possible heater/cathode leakage in AF section either first audio or output tube? Have you tried subs? Hum bucking coil miss wired possibility if you removed wiring? Just some ideas.

Edit: Cap #6 miss wired, note polarity with positive going to chassis ground. Other e-caps going to center tap with their negatives, not chassis ground.
