[HAM] CV Preamp rebuild

[Andrew Young]

Hi all.

I'm rebuilding my CV preamp (finally).  Everythings gone well so far.  I 
just have a quick question about the capacitor C6 which is a  .5 400v 
cap mounted to the outside of the chassis.

1) What is a good replacement value?
2) how to mount the new cap.

It will be nice to finally have this again.  The amp volume was very 
minimal.

Thanks.

Andy
