2x3.3 in parallel would be closer than a 3.3 as a replacement. 2x10uf in SERIES will be 5uf?
It is possible that TOO much capacitance would be worse than not enough....even if the 2x3.3 in parallel is closer.
Caps have 'tolerance', too. The measure of how far any caps individual measurement will be from the marked value.
some, the most common are 20%. Better is 10% while cost no-object can be 5%. The last get you into hi-priced goods.
In general, do not try to re-engineer a product. In some circuits, caps and resistors are chosen together. If you substantially change the cap, the resistor will be the wrong value. I don't know this is true, but you can probably buy tested / select caps of matching values. This is nutty, since nothing else in your amp/pre would than match, anyway.
Let me guess, you are trying to buy a better sounding cap?
If you are stuck on a name and they don't have the right values, you probably should pick another name.
