Analog meter reads 80 K.
Perhaps the resistance chart does not take the added SSB stuff into account?
U1 pin 1 and J1 pin 15 are both associated with this added circuitry.
I did the same build you did (well, on S/N 1641 anyway)...and noted the
resistance check values after adding the KSB2 components using a
Triplett 2030A DMM.
U1 pins 1 & 2 : 30Kohm
J1 pin 15: 31Kohm
So whatever the reason for what you're seeing, I don't think we can
blame it on the KSB components being present. You might want to inspect
things again. It's *very* easy to overlook soldering a pin or two on the
LCD or one of the processor chips, and have things sorta almost work
anyway because the pin's in a plated-through hole making intermittant
contact. I did that more than once.
