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. 73, Don W3FPR On 8/1/2012 3:30 PM, KC9QQ wrote: > I am currently in the process of assembly a KSB2 (REV E KSB2 PC Board) which > I purchased with my K2 in November 2011.
