Rick,

Look at that capacitor carefully under good light and magnification.  
See if that "330" isn't really "33G".  If so, it is the 47pF that you seek.
If it is marked "470J" then it is for certain the 47pF.

Sort your capacitors.  You should have 4 33pF and 4 47pF.  Once you have 
them all sorted and can compare the markings, it should become obvious.
The manual may show a disc type, but the type of capacitors has changed 
to mono in many cases.  The color of the capacitors has changed over 
time too.

One thing I can tell you is that you have a 2.2pF capacitor that is now 
labeled "229" - the '9' indicting that the decimal should be moved to 
the left by one place (9 is a negative 1).  That 2.2pF capacitor used to 
be a disc ceramic too, and is likely shown that way in the manual.

Sorry that this is confusing, but component procurement is getting more 
and more difficult as the industry moves to surface mount, and the 
sources of thru hole components is drying up.

73,
