OK.   Took out c22. 

Voltage on IC10 has returned  closer to the expected value. 

    Measured voltage for IC10 are:   pin  1  ~ 8   :   5.90 / 5.93 / 5.93 / 0  ==  6.08 / 5.90 / 5.93 / 11.87    (Volts) 
    Manual indicates :                       pin  1  ~ 8   :   5.8    / 5.8   / 5.8   / 0  ==  4.2  / 3.94  / 5.83 / 11.67    (Volts) 

Pin 5,6 has a higher voltage than expected.   But, it's not as bad as the 12 volts I was seeing on pin 1,2,3. 

I have to go source a 10uF cap now.  With all the small electronics stores closed around NJ, I guess I have to go to digikey ?  I don't imagine Homedepot sells these.

Will report back when I get it in.
