Review: Does the job well, brought an old guitar amp back into use - Bought this to bring an old guitar amp back to life. The board I received has dual 3A polarity protection diodes on the power supply input, enabling you to reach higher output levels more safely, similar boards I've seen only 1A versions, which could be problematic. Running mine off a ex laptop 20V 65W power supply , which is sufficient for my needs and it runs cool, load is a 3ohm speaker. Upgrading to a 24V 5A supply would enable it to get closer to the 100W figure, but at that point the heat sink is probably going to need assistance from a fan and I really don't need the extra volume. It is perhaps a little noisy at high gain, I've replaced the variable resistor with a regular pot and have a NE5532 based pre amp board feeding it, but once there is signal it's fine and in a guitar amp application, I'm not finding it an issue. Overall, at this price it's a pretty impressive board.
Review: Excellent - Works well. better than I was hoping for great job

### ⭐⭐⭐⭐⭐ Excellent
*by S***S on 13 December 2025*

Works well. better than I was hoping for great job

### ⭐⭐⭐⭐⭐ Perfect for a subwoofer
*by A***F on 30 December 2023*

I replaced my a/v receiver and didn't realise the new one required an active (powered) subwoofer. The woofer I had still sounded fine and so I thought I'd take a punt on installing this amp to effective convert my passive sub to an active one. Simple to install and works like a charm - every bit as good as the active subwoofer I have in another room.
