PLL circuit erratum. Builders please read...

There is an error in the circuit as posted.  It will appear to work as 
is, but the mixer has low amplitude and positive peaks are clipped.

I had corrected this in my unit but the correction did not make it to 
the final drawing.

I apologize profusely for this.

The drawing says to connect pin 4 of the LM324 op amp to ground.  This 
is incorrect.  It should be connected to the V+ (8 volt positive for 
FatMan) power supply.

Please accept my sincere apology for posting this with an error in it.
