Use Google or other search engine for the spec sheets. Component spec sheets can be found that way by simply typing in the part number and doing a search, most are in PDF form but some older stuff may be scans of original sheets.

LA4525 is a dual af pre-amp. looks like you should be able to use it for an amp but it is not a direct interchange for the 386. Down load the PDF file it has some good application data.

Check out the data sheets. Good application data.

LM386 can be bought at Radio Shack for around $1.25 (it's one of the few DIY parts most of the stores still stock) They can be orderd online alot cheaper.
