[Elecraft] Failed resistance check

[Peter James]

I have just completed (I think) Phase II construction of my K2, and I am 
getting ready to power up and calibrate.

Unfortunately, I failed a resistance check.  Page 59 of the manual says 
that the resistance from U6 pin 8 to ground should be >100 ohms.  I get 
about 37 ohms.

At first I thought this might be a bad thermistor, but looking at the 
schematic, even a direct short across the thermistor should not be able 
to lower the resistance that much.  I have carefully examined the entire 
thermistor board area for shorted traces or contacts with neighboring 
components, but I can't seem to spot any.  Are there other places/issues 
that could easily lead to the low resistance?  (I have double-checked 
that the right resistors values are in the right place on the thermistor 
board.)

I don't want to desolder the thermistor board unless I ABSOLUTELY have to...

Thanks,
