500ma is WAY to much! What you are looking for is something around 60-75ma. Here's a 15H choke https://www.tubesandmore.com/products/fi...15-h-75-ma
The resistance is a bit lower than your fc. If you don't use a series resistor it will increase the HV. With that being said don't think it's going to make much of a difference as the maximum plate voltage for the tubes in your set is greater.

I was down in the basement in my dad's
workshop. Perusing his Sam's Photofoacts
Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.

Now I think I've got!
