Same story here as Andy...
 
I  completed the first resistance checks on my kx1 over the weekend.  My 
readings (and confusion) are nearly exactly the same as Andy except my 
pin 5 resistance is  higher at about 33k.

I had taken a lot of care in putting this together as I haven't built a 
kit in many years but I rechecked placements, values, and solder joints 
just to be sure.  I stared through a magnifying glass between making FD 
contacts and then stared some more.  I resoldered some perfectly good 
looking solder joints figuring something must be bad.

Then. after looking back through past postings, I concluded that an 
infinite reading is >10k and I would press on, albeit somewhat 
nervously.  The readings for pins 1, 3, 4, 8, 19, and 20 seemed to be 
the important ones and other than that I was looking for shorts. 

Then I realized I had completely disregarded the need for a power supply 
so I'm on hold until my CUP-36 power supply arrives.   Well, I'm winding 
toroids, finishing up the tuner and 30/80 kits which I had used as 
warmup, and I will put together my NOCAL dummy load.

Did we go wrong someplace or is what we're seeing indeed OK?
