LM317 sounded awful - what's wrong with a resistor?

Posted by andy evans on April 13, 2025 at 15:07:55:
I've tried numerous active loads and devices in the cathode. In the end nothing sounded as natural and organic as a good resistor.

Don't ignore a simple resistor. Configure it appropriately for a LTP, maybe with a negative voltage if you prefer that.
