FS: 41hz.com Amp9basic Class D Amplifier

nic6paul · 14th March 2010, 07:15 PM

For sale I have a 41hz.com amp9basic amplifier I built a while back. I built with the intentions of building a home theater system around these amplifiers but I have abandoned the idea so this has been sitting on the shelf since then. I ran it for about an hour on a 12volt power supply and it sounded great. This amp is capable of producing 100watts into four channels. You can use up to a 24volt dc power supply but I have included a 15volt smps that I was planning to use with it. You will need to supply your own connectors for the header pins. I had made one that I used for the signal input but I have been unable to find it. I have since forgotten which jumpers need to be closed to get the amplifier up and running but I know everything was in the assembly manual. I would suggest reading that before attempting to power this up for the first time. I am looking to get out of this what it cost me to build it. I would like $80 plus the actual cost of shipping based on your location.

Please view the photos below to view the amplifier and power supply. If you are interested please shoot me a PM.

I want it. Just let me check whether it will work in car (12-14v DC).

It will work on 12-14v but you will want to present it with a 2-4ohm load. If you are interested in this without the power supply I can let it go for $60 plus shipping.

That's tempting, but the power rating for 14v operation is just 15W/channel, 30W bridged...
I'll get back to you, i need to think whether it will suffice.

I know others have used a 12volt to 24volt step up converter to get full power out of this in a car.
