Considering that the original resistors were probably 5%, I wouldn't be too
worried about the difference between 22M and 20M.

bit like the speedometer in cars, where every car seems to be able to do
240Km/H.

is a joke as well, what with certain manuf's putting green bands on dark
green backgrounds et all -- so I often simply measure resistors. Amazing to
see how far off certain values can be, even with 1% resistors.

exactly right (in the VCO) ? For instance, would a 20M (instead of 22M) be
good too ? (for lesser kludginess)
