pls upload your amp and tell us opinion and experience, or difficulties while making your own amp/ headphone amp. thanks

DIY (assembling) is pretty much a piece of cake if you had quality components and didn't screw up. designing and making ur own is another story


here is my Gilmore Dynalo, got 2 pieces of the board, suppose to build a balanced version but i guess i don't have that much budget atm...will only be using one for stereo. the one on the left is obviously the psu board. No idea how much is the retail yet as headamp.com did not show any interest in this amp compared to other Kevin Gilmore's amp. retail for Dynahi is USD1799....i guess Dynalo should be about 30% less. will be getting the parts tomorrow and expecting this to be completed(less enclosure) by end of the month....hopefully.
this gonna be my homeamp for some time...dont feel like feeding my sr-71 too much

EDIT: oh screw it.....transformer lead time May-03......
EDIT#2: ok, being a little cheap...sample opamps will be shipped in May 18, wont be seeing this baby in action until june but this delay save me RM120

WOW... so nice...alamaklor, can tell me where to get PCB or the OP-AMP to built Cmoy amp? i try to search in some electronic component shop in sarawak, failed to get it. so might request help from friend in KL to buy for me.

you will only need universal/multipurpose pcb to make a cmoy no need waste money to buy pre-etched and nciely printed pcb


I'm gonna stocking on parts for my Dynalo now, if you need OPamp please pm me, i'll suggest which one you should go with and the price. I'm starting a bulk in bulk section for OPamps and whatever electronics stuff.....check that out.

erk...can anione build me a headphone amp?

how much the average production cost for mid highend headphone amp?

yes, check out the bulk in my sig.

bout RM500

okie, got my parts yesterday, worked my @ss off and got the psu and amp part done problem is that i accidentally bought a bunch of 200"k" rohm resistor instead of 200ohm resistor so gotta order it again some missing caps and voltage regulators are in another order that i have not placed some pimping pics:

psu, amp, and solder side.

nice work there. i bought PCBs for the Dynahi sometime back, but sold it cause i didnt have the time and equipment to build it...plus im rather happy with my perreaux..

lol tyty.
initially i wanted to build a balanced dynahi, then i check out the cost and the expression was "wow, and ouch". well then i decided to go with balanced dynalo, bought the board and when i double check the order, it was anotehr "ouch" so in the end, a stereo dynalo

a headphone amp can cost so much, i had never think of it, however, is the quality good?

no $ to built 1, sigh

havent heard of it wor, still in progress as stated in above post. wont be seeing it until end of the month (end of may). cant get a decent heatsink that is < 2" tall. troublesome troublesome

btw, a palm size amp can already cost near RM2k....depending on the construction and design of the circuit.

alamaklor, try to look for CPU heatzink for 486 CPU? or mod (cut) it from current P4 headzink? will it be easier? it is soft to cut with powertools.

i need something quite short and wide. about 1.5" H X 6" W (or more) X 1-2" D. cant get something too small, must be within that surface area.

heatsink = heatzink = headzink?

alamaklor i really want somethings for make my cmoy, but the problems is i can't even get a standard PCB at my place... =~( not to mention the opa amp.

so u want me to get it for you?
it can be done, im gonna make my order soon...again.

can you pls tell me the price through PM? i really want it... i really sad for asking to some shop here : i want this this this opa amp.. you got? , then i get the answer : "what is that???"

i even print the photo of the opa amp and ask them to post for me. but guess what... they said that is not exits.... =~(

well, my answer would be: anything u want.
just click on the link on my sig and check out the site there for the specific opamp that u need, i've got a bunch here though and dude, do it quick, im really really really gonna order the stuff soon, end of this week probably. as for the price, just estimate 20% more (probably enough to cover shipping to msia) based on 3.9 conversion rate.

oh man..u guys indeed so PRO While LOADED!!

I dunno waht u guys talking bout...

How to start my first lesson bout creating Headphone AMp?
Any site for Noobie like me?

I mean start from baby language ...dun provide me like Master language..I will try to catch up watever i understand wif my capabilities.

thx.!

.tsk tsk tsk..this sub-forum got lotsa serious dude!

there are many sites out there that explain how to build a simple headphone amp, with a single voltage gain stage.

http://www.tangentsoft.net/audio/
http://www.headwize.com

AlamakLor, do u have any circuit diagrams for those headamp tat they'd built over at head-fi? I'm thinking of making 1 for myself... would help a lot if circuits are available coz it'll b valuable references....

headwize.com have a large collection, audiologica (tangent) have ppa, pimeta, mint, and cmoy(not really a diagram fro cmoy). kevin gilmore's site have a couple of his design up there. headamp.com have a couple of kevin gilmore's design as well, in fact, it's the final schematic for all his amps. best of all, design your own.

alamaklor.... so sad i don't even can get a PCB at my place... damn..

if you help me to buy all needed stuff for a cmoy, let say 3 pair of complete component, and post to my place will cost much or not?

RM10 to post to you just like pos laju haha but it will take 9 business days, about 2 weeks to be precise. just wondering if uw ant me to build the whole thing for you, i'll be picking some enclosure for some pocket amps that could tkae in 2 X 9v bout USD11 each.

Thanks ya. I'm gonna design 1... so need references... coz doesnt know how much amplification a typical H-amp need oso...

alamaklor, if complete cmoy set and u send it to me, will cost average how much? can get it below RM 90-RM100?
myself i think i need two.. because will use 2 headphone together ( me and my gf) when watching dvd movie.
but my hand also too ichy to try do it myself, but afraid spoil it also... =(

no way u can simply check out ebay to see what price they are running now.

Guys,
Got a question. What do you think of the DIY integrated amps compared with commercial ready-made ones, such as Marantz etc. In terms of cost/performance. I'm looking for such an amp for my entry-level setup, to match my floorstanding Wharefale speakers. Are there people out there who custom-make such int amps?

depending on the circuit, it's not easy to clone the exact same thing as different components are used so it's even harder to compare a diy amp from a commercial amp.

btw, it is called integrated amp because it is integrated into a receiver/player, better just use the term amp here.

some of the commercial amps have very simple circuit, some don't. usually, if u know what u are doing...it is cheaper to make your own than to buy a commercial one. sound-wise, really depends on what kind of sound you are aiming to get in return so usually the price:performance is better asthetic wise maybe not.

I'm new here...
Can someone guide me?
I want to build my own amp too...
Starting with low power ones...

there are 2 links in the 1st page where you may find very helpful

Anyone wanna form a Head Amp DIY gathering here? I am noobs here..Dun haf Electric-Brain & Electric-Tools... But i wan to haf a Headamp..

"btw, it is called integrated amp because it is integrated into a receiver/player, better just use the term amp here."


Minor corrections on the terms here. Integrated amplifier is when the preamp and the power amplifier is built in one unit/housing. Integrated amplifier plus a tuner is called a receiver. By this time you could have guessed what a casseiver will be...

Just my 2 sens worth...

TQ for sharing your knowledge.. =D

yes sir that is the correct term thank you for the correction

I prefer building tube amps. Anyone here has a nice source for good china made output trans?
Cannot aford those lundahl and tamuras ::

I plan to start my tube amp build with this kit. The slowly upgrade it.
http://www.diyhifisupply.com/diyhs_ella.htm

Weight: 21Kg <-- wow....

I think it's not realli cheap compared to other amp.... but the specs aint tat good.... Upgrading it requires some knowledge about the circuits, and the contributing components. I think AMB's M3 amplifier is almost the same price as the tube u're refering to. Sound wise, i think u could ask AlamakLor coz he's the only one tat's probably have access to these high end stuffs... But based on the specs and design considerations, i think it's a very good amp for high-end DIYers.

i built a DIY Cmoy amp a couple of years ago, and it's still working today. i used Burr-Brown OPA2604 dual-channel opamp (which is overkill, as it sucks the juice from the batteries like crazy).

the performance on my Sennheiser HD590 headphones: heavenly!
did i say it sounded heavenly? yep. HEAVENLY!

i built it when i was in UK, but here i don't know which shop can supply an OPA1302 (or other similar singla channel opamps).

but now my headphones have gone kaput: only right side got sound.

here are the pics of my amp. looks f**kin ugly, sounds f**kin amazing.

the guts


naked


in the case

u can get burr brown or analog device from rs malaysia(shah alam) or farnell(somewhere jalan 222 i think)

haha terkejut got same avatar with me, though i never post this msg before. hehehehehe i always cam the avatar any my start to know what post i posted when scrolling fast down with logitech cruise button. hehehehehe

anyone willing to DIY headphone amp and sell it off ..
im a willing buyer muahahahahahaha

error, contact alamaklor !

yay~~~ complete the list of part required to make the cmoy. i will study more about the layout before begin to make it. already have 100% component for 2 cmoy on my hand, except the housing for it. perhaps thinking of using some plastic or arylic to do it myself.

here here, what's your budget and what do u want on it?

blackflam interested with AlamakLor's product too!! Lai lai laiii.. AlamakLor going to >>BUILD IN BULK<<

lol.. you wont charge us so much ya, dear moderator~ *act cute n shiney eyes*

well if you a female with cute and shiney eyes, perhaps he will consider. if you a guy with cute and shiney eye, maybe he will charge you double....=P

Hahaha. Well, should I say "I am a lesbian trapped in a man's body" ?
forgot whose signature is that.. always seen that around. gavlim issit? lol.

AlamakLor, will you double charge me for having a cute and shiney eyes?

erm.. wait to see either alamaklor interested in a lesbian that traped in male body loh.

TAKE A LOOK!!!

i remember a us company, buying a china amp that looks almost exactly like the one you posted, rebadged it and sold it at a few times higher.....in the end the owner got caught but still denies it.
