[Elecraft] KPA 100 L15

[Soaring Eagles]

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.
