Question Interesting Gainclone type amplifier?

Looks like an amp for speakers like it mounts inside the cabinet, but look at the IC their using. Anyone know about these guys? I could totally use this as my forte is in speakers, but I'm getting started with Gain Clones.

They look OK to me and the price is certainly not a rip off!

I personally don't like the idea of the amplification electronics inside the speaker cabinet but if you don't mind that, you could probably build some very nice active speakers with these modules.

And they use 'genuine' WIMA caps too!

Default at least one person I know

in this forum has build an amp with the 4766 before
NewbieChipGuy If my memory serves me well....

I thought the results were very good.
Seems that chip price is decent, 2x30 watts according to OnSemi

this one should be made in order to compare with the 3875

i too have built an amp based on the LM4766. 40Watts per channel. it sounds noticably nicer then my LM1876 based amp (20W Stereo).

the chip is awesome - infact i even ordered 5 more of them so that i can experiement with bridged designs.

personally i don't know what eveyones phobia of the stereo IC's is?! they're brilliant (just remember to use a large heatsink). nothing beats them for simplicity of creating a stereo amplifier

there's a few pics at my site - sorry no good internal pics - i do have them , just haven't updated my site in yonks. the board design is EXACTLY the same as for my LM1876 as the chips are pin for pin compatible (altho the LM4766 needs a mute ressitor to take it out of mute) so you can get an idea of the layout by visiting the page for that amp

goodo

Interesting, those are my amplifiers - and my site! Thanks Mr. Resistor!

I'm kind of getting started with the 4766 as an entry level product aimed towards DIYers whose wives hate "ugly" amplifiers and for college kids that cannot afford to lose more space in their dorms.

I've sold a number of these already, though it's a surprise to see them here! I love em, personally (of course) and everyone that has bought one has been happy. That's why I do it!

I took the "genuine WIMA" out. YES, it was cheesy.

At the moment I have totally forgotten the name of this amp. It's mounted on a plate and the output power is 500-1000 watts and rather small (class D). Somebody else who knows?

No, that's a class D amp rated at 400 watts into 4 ohms and costing nearly 300UKP!
