Chip Amp Photo Gallery

Well that's just mean!

I want to see how you managed to stuff a useful amp into that tiny little box.

It must have been quite a feat.

Haha yeah it took some work... Everything fits well but it's just a box turned up side down with the parts attached to the lid. It was hell to solder and fix all wires. But I hear some ripple-noise , so I'll pop it open and cram some big caps in there and see if it gets better. I promise to take photos.

What are your speakers?

Klipsch KG 4.2 with Crites-mods and a lot of bracing and damping.

Made a 3U 'studio rack' for my 3-channel LM3886 & 2.1 active crossover. First time using a track saw, first woodworking project in years. Didn't come out perfect & there are certainly things I would do differently next time, but it's all a learning process!

Hello LE,

Lovely ply you used there very well done indeed. May I ask where you obtained the wood I had no idea such stuff was still available.

Cheers - J

hi,



i just managed finishing my first prototype of an lm3886 amp. everything is a little bit tight in there. i needed the small footprint because there will be 6 of them. there are 2 floors, the 120 VA 21V transformer is on the bottom and the rest is on top of it. cooling seems to be enough with cpu coolers i had as leftovers. maybe the other amps will get the same.

i noticed some slight hiss, i guess the reason might be input impedance or biasing. i'm not exactly sure about it, maybe i'll test it a little bit more.
otherewise i'm pretty satisfied with the outcome.

Hi Flexus,

The hiss may go or diminish greatly when your source is connected, even with it switched off.

You never know

Cheers - J

 

[flexus]

hi demraid,
right, its hissing when source is connected. its greatly source dependent.

Attachment doesn’t work.

Sorry Mark, it's been so long since I put a picture up I can no longer remember how, so I'm not sure how to fix it. I've googled and haven't had any luck, sorry to waste everybody's time 😞😞😞😞

 

[noviceimp]

Try this, my son reduced the file size for me 😊

 

[Sadface]

Nice build!

Just the metal back panel for the heatsink?

Now works.

I’ve probably asked this before but where in Oz are you from?

I'm a kiwi, lol. My name is Dave. Pleased to meet you, I've enjoyed your builds on the 4s tube preamp build. I've built a few of these now and exclusively use it in my system with my monoblock shown, I also use a second lm3886 to run my woofers in my open baffles.
