Building an old design by KK7B that uses NE5514 quad op amps (14-pin PDIP). Can't find a source for them. Have not been able to determine an equivalent currently available direct substitution op amp by cross-reference searches. Anybody out there know what I should use, or where I can get the NE5514s? Thanks.

I'd suggest getting that chip on ebay.com

This chip has a an output stage that works well in direct conversion receivers, where you need reasonably low noise and good output drive capability for maximum dynamic range.
