hello guys I wanted to ask you: do you recommend some amplifier chips to try apart from the lm1875 and lm3886.
There are several options. But the LM3886 seems to be what the commercial audio amps are still using. They build thousands of units.
have you actually built functioning LM1875 or LM3886 amplifier?
have seen your other thread, total disaster
have not seen your properly functioning chip amplifier yet, and you managed to mess up even kit to distort
LM1875 can sound superb, especially in transconductance configuration, even inverted is better than application circuit
go slow, you may go further!

you're right adason, 1875 already sounds very good, but if you tell me how, I can try to improve it, I really want to do. and to learn. thank you.
ISince I've seen the results, and how easy it is, Using pcb boards I got excited to try other chip amps.
I suggest reading of Joe Rasmussen pages and threads.
Tubes & The Gainclones
Tube Gainclone for DIY Buffs

Then read his transonductance thread.

I shiver thinking about how complex gain circuits such as speaker dependent current sources or complex potentially unstable multi chipamp layouts can work in this case.
I expect hundreds of posts threads.
I would stick to LM1875,now that it works, and ENJOY it.
Excellent amp.
Even LM3886 would be slightly too complex here.

I would just try this :An open source layout for LM3886? and you could find gerber files in post 58 (so you can order yourself some boards not to mess with breadboards ) . I believe this amp is just a little bit more complex than lm1875 amp.
Have fun!
Have fun!
hi asuslover, thanks, but the gerber file is that win zip? Who could I go to to get it done? Or if someone has one more could they sell it to me?
I hadn't seen that on diy audio store there are so many wonderful things, I'll definitely get something.
could anyone tell me something about gerber files?
how they are obtained, with which software, how to acquire already facts.
always thanks guys, (i'm studying adason)🙂

I see that many of these files are images how do you use them and then send to convert them to pcb ?
When you design a board you use a software pcb design, like Eagle, ZenitPCB, ORCAD, Kicad, EasyEda, PCBWeb Designer, , TinyCAD, Osmond PCB, BSch3V, ExpressPCB, gEDA, Fritzing, DesignSpark , diptrace and so many other ones...... the gerber files is the way you send your printed circuit board images(copper layers, legend, solder mask , drill data etc) to the pcb manufactures companies , I listed some in post 15.
yes i have seen companies, but these gerber files are images? for example the colored one I saw before when I went to the thread of 3886 you told me earlier
If you really need to see what pcb manufactures company sees in a gerber files just google gerber file viewer and choose one, the most accurate gerber file viewer I found was from PCBs cheap! - DirtyPCBs.com
