[R-390] wrong part in RF deck found

[JamesMiller]

It is SUPPOSED to be .033 according to common wisdom, so it was assembled
correctly.  Maybe the schematics are printed wrong in some cases, showing an
incorrect value of .003.  When you thnk about it, a B+ bypass should be
hefty in value, like .01 to .05.   The smaller value .003-.005 doesn't make
sense.  Put a .033 Orange drop in there.
