hello,

I've build a LM3886 amplifier recently.
When I start to play it works perfectly but after a few minutes the LM3886 turns of. After letting it rest for a minute, it works perfectly again, but only for a couple of minutes like before.
First I thought it was the powersink that was to small, so I placed a bigger one. Still, the same problem.

Then I read on a forum somewhere to measure on the output of the amp with a DC-voltmeter.
I measured while starting to play on the LM3886 and noticed that the voltage started around 1Volt to end up to 30Volt when it shut down.

Does this mean my amp is oscillating and what can I do about it?
Could it be because I haven't placed the inductor parallel with a resistor at the output?



Thanks, Robin
