Re: Never buy another 9V battery

Thanks for the info. I was looking at the "TL499A". Can anyone tell me if the pinouts
are the same? I have docs on "TL496c" and "TL499A" but being electronicaly illerate, can't decipher and reluctant to fork out 8 bucks to view all of that article. ;-)

you are Welcome here...
maybe someone can help me to find one. I have not a way to buy these here, in my country.

I hope on you, Folks of World...

You can nix the voltage multiplier circuit, and just run the detector off a 12v battery pack. Or use a more common ICL7660 (or equivalent) to replace the 496C.
