[Elecraft] low output on 12m/10m

Hi,
Finishing up my K2 (very recent rev B). All is well, except for the
following:
1. 40m tx alignment: pg 72 of manual (rev E) expects current drain at
5 W to be
1.3-1.6 A but mine is only 700 mA, similarly at
10 W,
expected drain is 1.8-2.0 A and mine is only 840
mA
I'm using two 100 ohm 10 W wire-wound resistors
in parallel as
my quick and dirty dummy load, if this is
relevant...
2. tx alignment: on pg 74 of manual - I successfully peaked output on
all bands
except 10m and 12m - in both cases I get the HI CUR
warning and
can only get 0.1 or 0.2 W out
I saw the app note on T2, making sure there's lots
of coverage
of both windings, and of elevating T2 off of the PCB
- both
of which I've done
I'll probably do the signal tracing (as a learning experience) anyway,
but thought I
might be able to fix this beforehand.
Thanks for any help,
Mike
