i don't know if anyone else has had this problem, but i have an audigy sound card, and whenever i listen to music it has this anoying echo effect that sometimes shows up. its not there all the time, just when i don't want it there. I can't seem to get rid of it, i've looked in all the sound...

i did, i've triple checked it

i might be wrong, but i'm pretty sure that, unless you want to buy resistors in bulk, you can't get metal film resistors at either place. I recomend getting polyester film type capacitors, thats what i got, and i'm verry happy with the sound. a cmoy isn't going to vary too much with the quality...

unfortunately, when i reconnect the pot, the same thing happens again. I COULD live without the pot, but its there and i would like to use it. i bought a linear pot because i found this http://sound.westhost.com/project01.htm a website talking about building a better volume controll, with...

don't worry about it... i think i got it, and i buypassed the ground, and it worked!!! both sides were equal volume, thank you verry verry much [so]hai YES I'M FINISHED!!! after i figure out how to reconnect the pot...

theres more wires in the final, that was a version before i connected all the switches and the pot and mini jacks. the V- and V+ of the op amps reads approx. 18 V, (i've got two 9V batteries connected) i'm not sure what you mean... i THINK you want me to bypass the pot with wires; tell me...

Quote: Originally posted by jeffreyj It no longer sounds like there is a problem with the amp; rather, I'd check the headphones! its not the headphones, i've checked...

heres two pictures. thanks for the help [edit] picture size

number one i'm using two single channel op amps, 123's i believe, also i've already checked connections, they are correct ground is connected to ground, right to right and left to left. i've looked over the board looking for unsymetrical wiring but can't find any... i have a suspicion (just...

its not that, only one channel is really quite, also, i've run a knife between all places that there could be a solder bridge.

bump

how... i built them on the same circuit board.... i've tries using the on/off switch for the crossfeed but it doesn't do anything.

anone else know how to get around the problem of LOTS of wires sticking out of their board? i know mine has tons of them and i don't know how to clean around them

i just finished building my CMOY, and i can't seem to figure out whats wrong: when i listen with my headphone plug in all the way one ear is loud, but the other is VERY quiet, however, when i put the plug in so that the ground of the socket is connected to the right chanel of the plug, and the...

so other than looks, scrubbing it with alchohol doesn't do anything?
