Well if you think more capacitance will help go ahead add some.
A .005 or .01 is fine. There isn't much voltage there even a 100v
cap would be fine. The .002 might have been used as a tradeoff
to roll off some of the low frequency response. By increasing it
value may increase the hum level.
One other thing use a GT style 12SQ7. Have seen where pin 1
was used as a tie point, not a good idea when using metal tubes.

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!
