If B+ is there then yes, you're right, the filaments are fine.
I would disregard the light for now and concentrate on sound.
He had Plate voltage on 50L6 so his output xfmr is likely good.
Need to check the speaker.
Try to touch pin5 pf 50L6 with a screwdriver (be careful, high voltages around, use one hand only and stand on an insulating mat if in basement), see if you have hum.
If not,
Disconnect the speaker from xfmr secondary and measure across the speaker with ohmmeter. Should be almost short, 0.45 ohm.

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
