Where to Find Vintage Stereo Manuals and Operator Guides

If you're like me, you've searched all over the Web for vintage audio operator manuals, service manuals, and the like. 


I've found two excellent sources for you. HiFi Engine requires registration, but it's free, and the AK (AudioKarma) manual database does not require registration to access the .pdf files, but does ask for donations.

Enjoy!
