I have a parts question on the K2 2nd Stage Xfil Mod, for 'Flatter' SSB
Filter Response.  In the parts lists it states components required:

(1) 1/4W resistor 3.3k to 3.9k Ohms
(1) .01uF capacitor (Low-Voltage OK)
(1) 120pF capacitor (Low-Voltage OK)
(1) NPN small signal transistor (2N4124, 2N3904, 2N2222, PN2222, or equiv.)

My question is how critical is the 120pF cap?  I don't see one listed in the
RS catalog.  Been through my junk box and some of my local friends and we
can't find one either (YET!)  Will 100pF work or will it skew the whole
thing? I have some time this weekend to work on it so that is why I'm asking
anxiously?! Tnx & 73...
