Hi, deniskin! My congratulations.
Shared amp version is just simple example of UcD principle.

ps: there is no need in ad825, you can successfully use tl071 or similar cheap opamp. [/B]
Sure, this prototype need protection circuit

ad825... I am have this IC in sufficient amount, no problem to use it

When you share a bridge amp? It designed to use a balanced, or unbalanced input?

Hi, mannycc!

Here is all docs: http://www.diyaudio.com/forums/showt...33#post1483633 .

Hi, deniskin!

can't say anything about bridge version, proto works well. Full balanced schematic applied.
May be later i'll finish this project.

ps: in fact, i didn't need such power levels

Thanks Bender, but that's the link I exactly mean because it's available for a couple of days only. I tried to open the your link and what appears is this; http://ifolder.ru/6153907 and it's end of the tunnel for me

thanks,
mannycc

hi all,

I assembled Bender.ru's Cakeamp V1, works well and nice sound!! but now i need more power (Too Much Power? Never! )... I wonder, did anybody try to get more power from that module, or anybody try to bridgemode (without Bender.ru) and can share schematics?

p.s. Bender.ru, how much power you get in bridgemode? Maybe you can share bridgemode prototype schematics?

Thanks for any Help!

Hello AmplifiersMan,

what choke you are using?
Epcos N87?

Can you give me the order code for the Choke,
maybe from farnell.com ?

Attached is a pdf for making the PCB with the toner transfer method. I hope Bender.ru doesn't mind.
