[Elecraft] Help with VCO Alignment on K2

I've run into another problem I can't figure out with VCO alignment
during construction of my K2. (very new kit, bought in the last 4
months)
I'm at the stage were I'm suppose to set L30 to get a 6v reading across
the left side of R30. (VFO set to 4000khz) I had originally messed up
and installed the wrong slug tuned inductor for L30, but once I fixed
that, I still can't get the right voltage. Right now I'm reading a
swing of about 8v down to 6.3v, the voltage is stable, I just can't
dial it down far enough.
According to the instructions there are a number of things I could have
messed up. I already fixed the L30 problem and I'm 99% sure I have the
right cap in for C72. The only other thing suggested is winding of T5
could be wrong, but I'm pretty sure it is correct also for two reasons;
first because I bought them pre-wound and second because I've counted
them several times.
Any other suggestions on what I could have done wrong? Would putting
T5 in wrong screw things up like this? I haven't got to the point yet
of pulling it off the board, but it was my next step.
Thanks,
