Why not just buy a 6 pF 50 V cap? Not like they break the bank...

What kind of application? For most applications a parallel or series
combination of ceramics or micas will work. Remember that it does not have to be
50 or 100v ... 500 or 600 or 1000 volt will do fine.

Now if its in a UHF TV tuner size may matter.

Do you have a radio shack nearby? They don't have much, but they do list it.

Here is how I temporarily replaced a 5pf cap in one my TVs:



Four 22pf caps in series gave me about 5.5pf. Not beautiful, but it worked fine.

Basically, wiring two of the same caps in parallel doubles their capacitance, and wiring them in series divides it in half. (That's the "shade tree mechanic" version of the formula, anyhow.) If you have lots of caps lying around, maybe you can come up with something that works for the time being.
