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.

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.
