[Elecraft] K2 C71 & C174

[Treat Hull]

Hi 

Having successfully build a K1 and a KX1, I have finally bitten the bullet
and gone for the "fully monty". My new K2 is going together fine, except I
can't find the 82 pf capacitors  C71 & C174. I know Elecraft will send them
to me, but I would like to keep up my momentum. I live in the greater
Toronto area, I have several good parts stores within ten minutes where I
can purchase replacement capacitors. My question for the list is: are there
any special requirements or specification, beyond capacitance, which I
should be on the lookout for?

Thanks in advance,

Treat Hull
