Hello everybody! I'm Doctor Nick! (err...or something)
well i've been reading these boards here for a while now and i've been reading em over at Headwize for a very long time as well...and finally i decided to go ahead and build a headphone amp. i've spent quite a bit of time researching and getting parts but it seems like everytime i turn around a newer better option pops up...well instead of riding that train i've decided to go ahead and build it with what i've got (i doubt it would make too much of an additional difference) anyways before i start i would like to know a few little things since i'm fairly new to this whole diy thing.
first of all i'd like some advice on the powersupply. originally i had planned to run the thing of batteries...but after some thought i came to the conclusion that A) i'm not gonna be taking this thing anywhere and B) i have a very bad track record for leaving things on and draining away batteries. sooooooo i would like to obtain an external powersupply. now i have a budget of about $25-30 and i was thinking something along the lines of a 24v supply would work...but i have no idea how to tell a good walwart from a bad...and reading through past posts really hasnt shed much light on this subject. any recommendations would be very helpful
also would i still need the rail splitter with an external psu? if so i'm curious to know why? also do dual output walwarts exist? in my budget?
second question: i have is regarding the op amp. i am planning on using the AD820 does this opamp require a browndog adapter? or any other sort of adapter? again although i've looked through old posts a lot of the information on this particular issue seems a bit vague.
third question: resistors...can someone help me decide on what resistor combo is going to be the best for me? i will be using HD580s the source (for the most part) will be coming from my computer and passing through my Quad 34 preamps tape output. i dont really listen to my music too loud but i do listen to pretty much everything under the sun. see below for all other parts currently in my posession.
Tangent's Meta42 board
C1 - dont have one yet...havent decided if i should... anyone have a solid argument for or against it?
C2/C3 - i have some 220uF 16v Nichichon caps
C4 - Wima 6.8uF
C5- none
POT - Alps Blue 100kAX2
blue led
3x elantec 2001 buffers
Neutrik locking jack
rocking toggle switch
2x gold plated RCA jacks
Black Hammond Enclosure
thanks in advance for any help
