Jim,
Sorry about the confusion I caused. I meant to say L16 but my finger
slipped. Yes, the board built from the Rev D manual will have no
component at L15 (and R12 and C82).
You will not have voltage at D13 unless you have connected a power
supply to the KPA100.

OK, now I'm confused. I'm currently building the KPA 100. I've just
finished soldering the finals. I currently have a blank space at L15. I
checked the schematics in my manual (Rev D, 9/25/06) and it shows that
L15 is not used. I also don't have any toroids left, and I wrote in all
the errata that came with the box when I got it (Jan, 2007).
Am I missing something? (namely a toroid). or an errata? I just checked
Elecraft's web site and looked at the schematic for Rev E (I know I
don't have it, but for comparison purposes) and it shows that L15 is not
used.
Thanks for any help. Just wanted to clear up my confusion before I got
too far.
Thanks!

.......First question is - do you have a red or a blue toroid core at
the L15
location? If it is red, you should have the Rev C manual and you will
have a voltage at the cathode of D13 with no power connected to the KPA100.
OTOH, if you have a blue toroid core at L15, you should have the Rev D
manual (be certain to download the latest errata sheet from the Elecraft
website). If this is your KPA100 level, then you will not measure any
voltage on D13 unless the KPA100 power is connected.
