I've been trying unsuccessfully to build a 2w headphone amp from an NTE990/LM377. It is horrendously noisy, so I'm about ready to throw in the towel on this chip. I've had success with an LM386, but it doesn't put out enough power.
Can anyone suggest a good 1-2 watt per channel audio amplifier with a schematic? The NTE was good because I didn't have to run it hot to get good amplification at the headphones (didn't run at the full 2w).
Space and efficiency are big factors, it will be running from batteries and carried on a person.
Thanks.
