For what it's worth I would say if the Kolster set uses the same tube lineup you should be in good shape to use it for the replacement in the Philco. For a year or so that lineup was a popular one but once the New Screen Grid tube(24A) became available 26's disapeered. You not have to neutralize them and have more gain. And you don't need that 1.5v filament winding. It's the only tube that has a 1.5v @ 1.5a. Anyway I'd give it a try but I'm CHEAP.
The important thing is that it has all the filament windings and center taps that the original had. If the HV winding is a little high that can be dealt with by using the right caps or changing it to a choke input.
My two cents

When my pals were reading comic books
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.
Circa 1966
Now I think I've got!
