Audion tube amp capacitor questions

I want to replace the capacitors in this tube amp. (Schematic here). Specifically the caps that are installed right after the rectifier. I am wondering if the Panasonic EE series would be suitable for the application. I've read that you need high ripple caps in this location, and these do look suitable to me:

Datasheet Panasonic EE radial

I am thinking about replacing the four caps (100uF/100uF/75uF/25uF) with four 47uF/450V caps instead, since other values have been hard to find. Is this a good idea?

Any help greatly appreciated. :)

Unless you can understand and recalculate the effects of a change, stay with the values of the original circuit (plus or minus 20%). You can always parallel two 47uF caps to replace a 100uF cap.

What about the series itself? Will it be suitable? There are other values.

Looks good to me, 105c ratings are a must for tube amps.
