Re: U1 fried

The chip is rated to work with a 4Ω load so a 4Ω resistor should do. I doubt the chip would blow so fast that FB fuse wouldn’t protect it.

Better be a pretty darn fast fuse.

I'll go with an 8 ohm 1/2 watt series resistor to limit current.
At least till I find a good source for TDA2822M chips.
I'm fairly certain that resistor will offer sufficient protection.
