I have PCB + IC for this awesome Gainclone amplifier by Pavel Dudek.

sjostromaudio.com - PA03 Pavel Dudek's deLuxe Gainclone

All manuals, schematics, BOM, PCB details and design help is available on above website.

There is a whole Wiki about this project on DIY Audio website

http://www.diyaudio.com/wiki/index.php?page=LM4780+Pavel+Dudek+GB

You can find a lot of discussions & praises about this project on diyAudio

This design has frequency response of 10Hz-140KHz with tons of features like built-in power supply, slow start, mute, pre-amp, subwoofer cross-over, lots of protection circuits etc. This is undoubtedly one of the best PCB in market – can be used in stereo or subwoofer (bridged) configuration. One has to see this PCB to know beautiful piece of PCB craftsmanship.
Price is 400 SEK + 55 SEK for shipping (around Rs. 3100/-, 1 SEK = 6.87 INR)

Expecting ~Rs. 2000 Shipped - Open for offers including barters via PM. Includes one PCB + one LM4780 + two Inductors. Rest of the components are available in the local market.

All the details about this on above websites. PM me if you have any specific questions. Also including picture from Pavel's website.
 
i cant download any "All manuals, schematics, BOM, PCB details and design help is available on above website"

is there a username and pass provided when you bought the thing

what does the total cost of the project work out to? do you have a idea
 
hmm, that site appears to be under temporary maintenance and should be up soon. If not, I will get it from my archive and post here.

The major cost is PCB & IC, which is included. So you should expect Rs. 200 to Rs. 700 depending on the quality of components you would be using.
 
Sorry to be a n00b ..but can you tell me what input and output connections will this use ? will it b e 3.5mm ?

Also can this be able to power up a Headphones of 32 ohms ? Philips SHP 9000 to be precise ?
 
It's 120W amp. Overkill for headphone :)

Ideally suited as very high quality, low distortion 2 channel amp or a subwoofer amp in hi-fi system.

Best
 
It's a gainclone/chipamp, meant to drive stereo speakers with fairly high power - something like 2 x 60 Watts or thereabouts. That's way too high for headphones - look for a Chumoy or similar circuit for headphones, for which 0.1 Watts output is more than sufficient.
 
Hmmm...Where to get components?

and what would be appox cost of total project if I decide to built a Stereo Hi-fi system, a 2.1 Setup.
