SOME INTERESTING TECH VIDEOS

here's a few interesting audio electronics related vids i pulled off the net.  i haven't had a chance to check them out yet, but i thought it couldn't hurt to post them anyway.  check out the other videos on the channels of the posters, there is some good stuff there as well.  

cheers!

gigelmargel's CRANKED AC

here is a pic of an assembled cranked ac pcb put together by FSB member gigelmargel.  looks great, and thanks for verifying the project!  the full project files can be found here-

SOLID STATE GUITAR AMPLIFIERS BY TEEMU KYTTALA

clicking on the title of this post will send you to a download page for the book SOLID STATE GUITAR AMPLIFIERS by TEEMU KYTTALA.  trust me, DON'T be dissuaded by the title!  even though sold state amps are kind of like kryptonite to many tone whores, this book contains tons of info that can be extremely useful when designing audio circuits.  explicitly the preamp section, which is full of heaps of goodies that can be used for stompbox design.  it's written in a simple, yet concise style that tells you just what you need without getting bogged down by too many details.  also, the power supply and power amp sections have everything that you would need to build an ss amp. this book really is a great resource that i will be diving into head first.  i believe teemu goes by teemuk on the forums, so make sure you give him a hearty thank you if you download the book!

THANKS, TEEMUK!!!
