I have a couple of Sure TA-2024 15W class D amplifier boards for a sound art project and need the simplest minimum parts preamp to drive these from Arduino microprocessor output pins.
For testing I've been using a resistor divider to bring down the 5V output and feeding it to a tube guitar amp (which sounds great), but the Arduino doesn't drive the TA almost at all. Can I preamplify the Arduino output with a single transistor? I have 5V and 12.5V available to work with. Any ideas appreciated.
