Jeremy,
That voltage is close to what I would expect from a new Lithium battery.
If you are measuring an Alkaline battery, then your voltmeter is a bit
on the high side.
So if Alkaline battery, then your 0.65 measurement is likely OK, but if
that battery is a Lithium type, the bias is a bit high and you may have
to experiment with slightly different values at R60 to bring the bias
voltage down a bit.

A new AA battery right from the package is giving me 1.615V on the fluke
meter. This is a newer K2 (#7405). I had some issues when building it
which caused me to go through a couple of sets of PA finals before I had to
send it to you to get sorted out. It was working great until now, so
hopefully there isn't something residual that is creeping up now. The
resistor values are all correct according to the manual.
R59 4.7k
R60 100
R61 120
R62 2.7k
R63 220
I am performing the voltage measurement on the Base pad of where Q8 would
go, and pressing and holding the "Tune" button on the front of the radio.
