Hi

I think you have the 10/12 meter bandpass and ALC mod confused with the 2nd
xtal filter mod. The KPA100 comes with the former. There are several more
mods in addition to the ones you have installed and the PLL/BFO required to
bring your K2 up to "B" status. The kit and instruction will be available
soon. I have a "B" schematic and I count at least 19 mods total to bring a
Rev A to a Rev B.

1  PLL
2  BFO
3  D10
4  ALC
5  10/12 meter
6  RFC15
7  RFC11
8  add C28,29
9  change value C30,36
10 add C224
11 change value C225,226,227,L25,L26
12 audio pot mod
13 sine wave side tone
14 AGC threshold
15 voltmeter switch
16 added filtering on voltage sense
17 D19,20 and C71 for future 60 meter option
18 change R60 to fixed 100 ohm resistor
19 new crystals for CW and SSB
20 ??
