Default inexpensive analog audio pitch (frequency?) meter or schematic / plans for one?

National Semi still makes a "frequency to voltage" converter chip,
so does Analog.

But here's a link to using a PLL -- from National Semi --

This is fine, but what about the accuracy and resolution of the analog meter
used to read the output?

It still isn't clear why the OP is insisting on an analog display.
