Well....the 12AT6 came last week and the 50B5 came today, after, according o the seller, having first returned back for invalid address.
To add to that, the tube was supposed to be a Philco.
That one.

If you look, this below is the same photo, but says the different tube.

In fact he has bunch of Philc tubes listed with the same exact photo.
What came is an RCA in the RCA box. I am not even sure the glass marking is the same in the picturre.
But it is a 50B5 and tests as it should.
Anyway, the hum diminishes just a smidge after changing 12AT6 and I am not even sure it is not a wishful thinking at play.
Went through the chassis....no non-conformances present.
I decided to throw in the towel. It works, with that resistor decreasedbit doesn't hum too bad, so....

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.
