R6 shows as 47 Megaohms on my schematic.



22 Megohm is the highest standard value. Anything higher is either
special order, or made from a group of lower values.




My bad, it is 4.7 MOhms . Bad eyes, did not see the period between the
numbers. R6 is between a transistor Q1 colector and a 741 opamp with a
22K before it and a 100K after it.
A missed period has been know to cause large problems.
