Hello..
I am a long time lurker with very few posts.
Finally i mastered the energy to get my lazy butt out of the chair and build a headphone amp.
I used a Texas Instruments TPA1517 for the amp.
Below are the results.
It is not fully complete as i have only finished fabricating the board.
The chassis and the works are in order.

HDamp

PSU Board
Amp board
The PSU receives its supply from a 10va trafo with 12-0-12 stepped down from 230-0
The 12-0-12 is rectified , and regulated (7815) and filtered
PS: it is my first time building something and that too with SMDs
feedback is appreciated

An externally hosted image should be here but it was not working when we last tested it.

@pacificblue
it does
but i m not using a 4 ohms load.
i am using it to drive a 32 ohms headphone load.
the only heat dissipated is the difference between the input voltage and the regulated output.
i am using it with a heatsink, i have just not shown it in the picture
once the chassis is finished i will post updated pics again.
@kuldeep
I have tinned it using lead, 25w soldering iron and a solderwick
the fastest and least cumbersome way to tin it..

no mate.
i used plain , run of the mill solder wire (60-40)
first
apply flux to the entire board.
let the iron become hot.
tin it
not take a small quantity of solder onto it
Let the flux core evaporate( i assume you are using rosin core solder)
now use the iron as a paintbrush and coat the entire board in fast, small strokes
Cover only a small area once
and DO NOT use excess solder.
You are only trying to tin the board not solder anything onto it.
(A small droplet of molten solder can be used to coat a 1 inch x 1 inch copper clad fully.)
Now flux the solder wick
Now use the solderwick as a mop to remove the excess solder,if any, over the tinned tracks.
It is pretty easy mate.
Do one board and you will get the hang of it from the second board itself.
PS : Do search youtube for "tinning"
It will give some helpful results
meanwhile see the video
It is much more useful than a page of writing..
