Headphone Amp (Chu Moy)

Step 10 Enclose it!

I didn't get any images of this as it is pretty straight forward, drill a hole big enough for the part to put through and well, put it through the hole.

REMEMBER: to insulate the bottom of the tin using insulating tape, foam or a cut rubber mat. This will stop shorting.

once its done, enjoy!

I also entered this for the thinkgeek competition as not only did i buy the tin from thinkgeek but they also offer a mint tin cmoy, this shows you how to make that famous thinkgeek product.

Thanks so much for putting this up! I had issues on my amp I tried, and really alittle on the second, I couldn't get any right output. After my first complete failure I decided to order higher quality components but once it was built same thing bad sound in left and no right. I ended up taking the 10k pot out and that seemed to do it. I still have an issue when I move the amp but all I have to do is turn it off then back on and it works. Any ideas why? I checked all my joints and it looked good to me.

Would this work with about 5 outputs for headphones?

nice mate, and this can make other stuff louder right?

i have a speaker that is 2" diamter, and the back part is like 1 1/2" it doesn't have anything on the back of it, and i was thinking about making this to make that run louder, i hooked up my bookbag to it, and it can fill a quit math room with music, :)

nice job! a little question... i can do this (mono obviously) for making a boost pedal for electric guitar?. thanks in advance .

it's probably not powerful enough to be used as a preamp, but you can certainly try. not like it's expensive or anything. plus, if it doesn't work you can use it as a headphone amp.

It is quite powerful bt u will need gain of 100 to use it with guitar....nd cmoy runs on gain of 1-15.......bt it is easy to make it 100 just change the resistor !

[Zem]

What would you change the resistor to for 100?

[shams]

It's not resistor it's the gain of amp.............higher gain means it will amplify more lower power signals to higher power signal......bt can suffer with distortion....so watch out !!!

[Zem]

 ... You said "bt it is easy to make it 100 just change the resistor !" what am I changing the resistor to??

[shams]

Gain=R4/R3+1.......this r two resistor in feed back loop.........

 Ooh, okay thanks.

Great job!! I will be trying this out myself.
