Hi and welcome,
As Mike mentioned the better choice is to use film caps for the power supply filters. I serviced a Philco 87 which has a similar style power supply and use several pair of 4.7mf @450v electrolytics in series to equal abt 2.3mfd. All went well but after abt 6 months of uses the input filter shorted and nearly took out the 80 rectifier tube. Wouldn't use ecaps in these late '20 and early '30s sets.

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.

Now I think I've got!
