[sdiy-interim] Fwd: PLL (4046) for pitch tracking?

[Loscha]

Don't believe the manual!
It functions in it's pitch tracking mode over quite a wide range ---
it outputs a toothy wave to the "tuner out" port on the back in pitch
mode.

This is my scan, from a schematic I purchased, hope it helps some people out.
I have the rest of the manual, if anyone needs a hand to get their
RPS-10 calibrated.
