Fred,
Look carefully, that new manual does not match your KSB2. Yours has an
SSM2165 Speech Compressor and the new one uses an SSM2166 - the added
resistors support that new IC.
As far as the extra 10k resistor, one is supplied with every KSB2 for
use as a bias resistor if needed. It is listed in the parts list as a
component on the front panel.
