[Elecraft] [K2] VCO Not Oscillating

[Joseph Baxley via Elecraft]

Don,  Matt,

I looked at the transformer and have double checked him.  I saw that there
was electrical continuity between leads 1 & 2 and 3 & 4 (i.e. zero Ohm
resistance between said leads).  Also, 3 & 4 are the green leads.  I checked
that the green wires weren't crossing and that they were spaced each turn
between the red wires.  I did notice that they weren't exactly centered,
with more red turns before lead three than after lead four.  I pulled the
transformer out and rewound the green wires to center them and see if it
helped any.  No dice.  Also I checked the number of turns, 16 red and 4
green.  I'm intimately familiar with not having properly stripped the wires. 
That was a problem building my K1!  

I'm fairly certain then that the transformer is not the problem.  I've been
checking things like the diodes that run through the VCO to make sure that I
have not put in one backwards.  I've also been looking for cold joints or
solder bridges.  Haven't found one yet.  

Thanks,
Joseph
