Well all for best results. The big one definitely! It's a mess to take apart and clean the tar. After that it's a piece of cake. Keep the value of the input cap the same the others aren't as critical.
There are a few bakelite block caps and a metal can with a few .25 or .5 in it if memory serves me correct. When you replace all it makes troubleshooting easier and you don't have to keep pulling it apart time after time when another one fails.

>Actually, it was my intent today to measure the capacitance of those by de-soldering the surrounding wires. I wonder myself how they have survived these 80 years
It's the leakage that is problematic.

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 it!
