How do you connect the Poly Variable Condenser ( it has 3 pins) to the TDA7000 FM Receiver which only requires 2 pin for the Resonator part of the circuit.
i need that 2-60pF range of the PVC and i want to know what will i use between those 3 pins.
The technical spec is here --> http://mzentertainment.com/technical_archive/TTWM_variable_capacitor.gif
and here's the spec:
TTWM Poly Variable Condenser / Capacitor.
Two section, apx 60pF and 140pF max.
Commonly used in portable transistor AM/FM radios.

I would like to post the schematic, but unfortunately, the website was down at the moment.
But getting that 2-60pf in series with 56pf and parallel with 33pF and 56nH inductor will provide a 85Mhz to 113Mhz
