[sdiy] OT: Turnrable pre - converting from moving coil to magnet

[Nathan M. Reeves]

Funny I googled for "phono preamp schematics" just yesterday....

I am looking for something that is hifi but easy to build (read novice)

Some of the more interesting finds are

http://diyaudioprojects.com/Chip/Phono-Preamp-Kit/

http://www.geocities.com/TimesSquare/1965/phono.html

Also PAIA had a kit...

http://www.paia.com/riaa.asp

Again, I am looking for something very simple but meets the RIAA eq  
curve standard....

Any kits I missed?

sorry for the thread hijack! :(

cheers,

nate
