new cmoy type amp

inox · 7th December 2005, 11:32 PM

yeah im new here so i was wondering if anybody could give me a hand
im trying to build a cmoy amp that is specifically for a bass guitar
this is the tricky part i need it to run off of one of the large 9v batteries
im hopeing to get it to power a small speaker that will be loud enought to hear clearly even if it doesnt sound the best

one should be able to modify a cmoy circuit to power either headphones or a 2-3 inch speaker easily enough but i dont have enough experience to do it myself

basically i want to build this for personal use as in if its just me ill use the headphones but if im playing something and want some one to hear it i can unplug the headphones and they can hear it also maybe not all that loud but clear enought that it sounds right

anyhelp is apereceated
i dont know enough about amplifiers to do this myself and some one sugested i post this here so i hope i get some good help thanks

A Cmoy amp is a single op amp, which is not enough to run a speaker. You'll need more than 9 volts to get much power.
