[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
