Hi, If you're serious about "professional" grade preamps, Tape Op published an article describing preamps. It included schematics and kits for assembly, just in case you don't want to do all the work. These are vacume tube solutions that cost about $400.00 US per channel but are in the quality range of $1,000.00 devices produced by companies like Avalon. Sorry, I don't recall the title of the article, or the publishing date. Perhaps you can find it on their website, www.tapeop.com. Incidentally, Tape Op is an interesting publication for the DIY types. I mention this because I've noticed there's a couple DIY'ers on this list. :) ron > schematics, eh? > Depends what kind, but there's lots of stuff > floating around... > http://www.newmex.com/f10/taosamp.html > http://www.waltzingbear.com/Schematics/Schematics.html > http://www.jensen-transformers.com/apps_sc.html > > google for "mic preamp schematic" will give you lots > more... > > -- > > Paul Winkler > http://www.slinkp.com > Look!
