I've finished my Millett and i get fine sound from both channels....however i can only turn the bias down on the left channel to around 17.5 until the the trimpot starts clicking and won't go anymore....the right channel can be adjusted from around 6 on up. Again it sounds fine but is there some...

So i found out what was causing my problem, turns out the power supply i was using had this replaceble plug mechanism and the plug was put in the wrong way. Now the amp turns on with the led and i can adjust the bias, however there is no sound coming out and on the left side the bias can be...

Ok so i went back to my amp and realized my d1 was put in the wrong way. I replaced d1 and pf1 and put in d1 the correct way, however i am still having the same problem as before (the pf1 gettin really hot and the led not coming on). What damage could have been done by mounting d1 the wrong way...

what does it mean when my pf1 is extremely hot when i turn on the amp....also, the led doesnt turn on....is it simply i have some cold welds somewhere or something else, like would that problem be able to tell me exactly what is going wrong with the amp

i've gotten all the parts on the board except for the components like the power and inputs and outputs, i assume that s1 and s2 are for the switch but i only see a v_in pad and was wasnt sure how to connect the power exactly. wouldnt there be a v+ and a v- from the power to connect to the board...

im in for 2 boards

i was readin some old posts on how diycable.com had cable kits. they apparently had a "skinny" kit and a "fat" kit. well i went to diycable.com and i guess they dont sell the "fat" ones anymore (correct me if im wrong) but they do sell a kit called superlative. im jus wondering which is the...

i am planning on building my own PPA (man its prob gonna take me forevr to get it to work right) and i was wondering what kind of R4 value i should use on the PPA amp if i plan on using the cd3000 with the amp. also, would using the opa627 op-amp be a good fit for my the cd3000, sorry if these...

i was wonderin, how well do the px200's keep the music in. Like if i were to hear my music very loudly, how much would people sitting next to me hear.

i finished my cmoy amp and my problem is that the sound comes through even when i dont have the power connected to the amp. is that supposed to happen? also when i do connect the power and turn on the amp, the sounds seems to not be changed. i dont kno what to do.

let me change my problem a little. i only connected the output jack and thats where im gettin the sound. so whats my problem

when i give power to my cmoy i get this constant sound that sounds like a loud helicopter. i dont even have to pass the music through it to get the sound but when i do connect the music it makes the same sound. im thinkin i might have a problem with my ground. if so how do i fix it.

i built my first cmoy and the problem is that the music comes through but theres a lot of static and its at a very loud volume all the time. i think my problem is that i connected the jacks and pot incorrectly. i cant read the schematics for the jacks and pots so i dunno which leads are the...

can i jus strip copper hookup wire to use as jumpers for my board?
