Hello everyone,
For the last 2 or 3 years I have been quietly reading everything I can find on this forum about the LM3886 chip amplifier. This is because I have been building a dual mono amp with this chip for many years. It started as a small project. I had a pair of speakers and no amplifier to drive them. Now I am far down the rabbit hole. I have tinkered with a point-to-point setup and designed a few PCBs.
The latest board I want to talk about in this forum. It suffers from oscillation when the output voltage reaches the rail voltage (and while clipping). Perhaps someone has some advice on how to fix this?! More about this later in the chip amp subforum ;-)
Regards
Sven

I just read something about proper decoupling to prevent oscillation.
