Your screen voltage is almost the same as the plate voltage.
Higher screen voltage will make the tube bias MUCH hotter.
You could try sticking a 2K-5K resistor from your choke lead to the screen lugs.
That will lower the screen voltage a little bit and cool your idle current a few ma.
You still will have more screen voltage the the rest of us!
Other then shorter power tube life, I don't see anything wrong with what you are doing if the power tube's plates are not glowing red after playing hard for a few mins.
