400 volts would be fine for 32,32a and 32b just to keep it simple. You can use 10 mf subs.
Note that 32 B has positive lead to ground! Won't work if you get it wrong.
Figure on replacing all the other small capacitors (tubular and bakelite,) I'd add to the order a set of silver micas including those in the if cans, as you may have to replace one or more anyway, and for the couple of dollars I'd order fresh resistors and go ahead and replace them when you do the cap job. So one order, ya got everything. Makes a big difference when alignment time comes, and adds decades to set's life.
Just Radios is mentioned often and Jameco hobbiest friendly, lots of others too like Digikey, and others.
