I'd just Google for bandpass opamp

for example

http://ourworld.compuserve.com/homepages/Bill_Bowden/opamp.htm

http://sound.westhost.com/project63.htm

Or something like the LM567, which National say is discontinued, but
you may be able to pick one up somewhere

http://www.national.com/ds/LM/LM567.pdf

They still do the MFx range of filter chips, like the MF8

http://www.national.com/pf/MF/MF8.html

although the highest centre frequency is a bit low maybe

Microchip make a range of devices that could be used

Frequency-to-voltage, opamps and particularly FilterLab s/w
