K2 parts number questions

[Paul Huff-3]

I just finished an inventory of my K2 and I have a couple of quick questions.

1)  For several of my SIP resistor packs, my part has an extra "C" in the
number.  For example the manual will give the number as "770103471" and my part
is "103C471."  Am I correct in assuming that these are the same?

2)  I am more puzzled by a couple of capacitors that I have in the kit and a
couple listed in the RF board parts list.  I'm not sure that they match up:

- The parts list gives C33, 2.2 pf, NPO, "2R2" or "2".  I have a small orange
disk with a black tip that says "2.2".  Are these a match?

 - The parts list gives C22, ??? pF, NPO, "2R7", "3", "3.3", or "3R3".  (The
value in the manual is not printed correctly, but I think it's supposed to be
3.3 pF.)  I have a small blue cap that says "2.7C" on one side and "1 A" on the
other.  Are these a match?

BTW, "C22" is also used to designate a variable capacitor, but I think that this
"C22" is a fixed value in the 20/30 meter band-pass filter.

Thanks in advance for any help that you can give!

Paul,

Parts manufacturers often put extra numbers in the designation, some are
meaningful for the package configuration, but others are for some coding
used by the manufacturer.  Just go by the last 3 digits - that is the
value code, 471 would be 47 followed by 1 zero, or 470 ohms.

On the capacitors, 2.2 and 2R2 are the same as are 3.3 and 3R. - the R
is often used at the place a decimal point would be located.

There is a variable C22 on the Control Board, but the C22 capacitor on
the RF Board is fixed capacity.  I hope you are inventorying the 3
boards separately because there is overlap of the part designation on
the 3 boards (in other words, there will be 3 different R1s, 3 different
C1, 3 different RP1s, etc.
