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.

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....
