Head-fi, I know this probably isn't the best forum for this, but does anyone have any suggestions for powering a 7.1 channel power amp? I currently working on a multi channel amp (gainclone if you must know), but I have only experience wiring a 2 channel amp with a torodial transister...

I want to hook up my mp3 player to my car stereo, however I need a line out. So my idea is to remove the opamps from the output of my Creative Jukebox and therefore making it a line-out. Will this work?

Ok guys I have an old m700 700mhz compaq armada laptop that is giving me alot of noise. Its NOT the 60hz hum, its NOT RF interference from outside sources. I get noise mostly from my HD and ethernet beinga accessed. Has anyone experience this? Any fixed? Problem: I can hear noise, lots of...

I'm looking for a couple of these transistors and am having a hard time finding these in the states. Does anyone know where I can buy some or is anyone willing to sell me a couple? I'm looking for 2sa1358 & 2SC3421, 6 of each. Thanks.

Is there a way of putting a SMD, specifically a BUF634U, from the TOP layer of the board to the bottom?

I'm looking for a quality Transistor, preferrably in a TO220 package, but any recommendations are appreciated. Just for reference these will be used in a diamond buffer for a Pimeta amp. edit: can anymore help me out and tell me about the differences between a "power amp transistor" and a...

I'm a little comfused on the numbering scheme used for Surface mounted resistors can anyone educate me? Such as the resistor I have says " 4R7" so whats the value? I have another that says "330" and another that says "221" are these their ohms. I've heard alittle about three and four digit...

Ok well because of a recent thread I want new speakers. I've had my z560's for awhile but they are too boomy and don't have enough mids. I'm NOT looking for a small 2.1. I need something a little bigger, without going and getting a dedicated setup. Plz don't recommend some ****** Creative...

I don't know if this has been posted before, but I stumbled across this link. Basically a test was done to see if cables really do matter. http://www.hometheaterhifi.com/volum...s-12-2004.html " The total number of correct answers was 73 out of 149, which amounts to 49% accuracy...

Well since I can't find an enclosure that I like, I've decided to custom make one and see what happens. Does anyone have any links as to how to go about making a case for a small amp? I have no idea where to start. The board will be about 4" X 4".

OK so I removed all 4 output caps aswell as the output buffers. From this thread http://www4.head-fi.org/forums/showt...light=0404+mod Now I get no sound. Everything is working, foobar does give me playback, and Patchmix shows the card working, but I get no sound. Help! I think the...

Well I think I've hit the wall with smaller opamp based amplifiers (pimeta,PPA) and I'm looking for a different amp to contruct. Can someone please explain the differences between more high end amps such as Gilmore Dynamic, Dynahi or any tube amps. My current setup is a PPA (soon diamond...

Is there anyway to modify components on the FLY in Eagle? Meaning I want a little more spacing, is there anyway to move the Via's of a transistor out a bit? thanks in advance to anyone who can answer this. -dan Edit: On the FLY = while at the board.

Ok so I've been messing with the FX in the 0404's PatchMix. The only problem is that they only work in 44k & 48K. Sooo I took off resampling in Foobar and started to play. Oh boy what a surprise was waiting for me. The Equalizer's in PatchMix run circles around foobar's. You can specify...

Ok I'm messing around and throwing together a Pimeta just for fun. However on the schematic on tangents site: http://tangentsoft.net/audio/pimeta/misc/schematic1.pdf On the power supply what are M- & M+ ??? P.S. I'm printing my own PCB.

How do you represent a TLE2426 railsplitter in this program? I can't find it in the library ??? Help! ::bows to DIY gods::

Wow just wow, I just finished building my PPA, replaceing my old CMOY. All I have to say is that the bass is now earth shattering!! It is now confirmed these things have bump. /end shameless basshead thread. P.S. I don't even have the bass boost in yet, i can't wait! -Dan

Ok so first off, look what i did in the past few hours: I just turned it on, and tested the power. Everthing OK! I can't believe I have gotten this far. I'll save my "Thank You's" till i finish it, hopefully tomarrow. Anyway on to my question. Since I wasn't able to get into that 99.999%...

Why didn't anyone tell me Pink Floyd was so good? huh? why? I haven't been this impressed with a CD since I first heard Shpongle. Although they are different genres, I am completely blown away! I got a hold of this BEST OF CD and well I can't put it down, or turn it off, whatever. Echoes is by...

Well I'm about to start this project, yet there is one thing i'm not 100% sure about. What is the right way to solder components onto the PCB board?? I was under the impression that you always do it from the bottom. With the board upside down you bend the leads to hold the component in place...

OK well all this talk of EQ's and bass in the other sub-forums had me thinking. Alot of purest don't like EQ's but I love them. So I'm going to post my settings and if anyone wants to try them and see if they like them more or less than their settings please post. My settings are the same as the...

Has anyone changed those uncomfortable pads that come with the A900's to something more Sennheiser-ish? Would it be possible to put DT880 pads on the A900's???

how many C 2/5 do i need 8 or 16???? (Maxed out PPA)

Well i've finally decided to take the plung. With credit card in hand I'm about to purchase all the parts needed, listed on Tangent's site. However before I spend 200+ on this I want to know if there is anything I should take into consideration that is NOT listed on his site. Such as, buffers? I...
