It's alive.

TPA3132D2 aka TPA3116/3118 derivat in smaller package.

Claimed to be something like 50+50W Stereo or "100W" PBTL.. Well, lets be serious.. 2x25W to 2x42W.. something in between.

Running well at 400kHz or 1000kHz.

Don't know how much power...chart says 32W / 8R / 1% but speaker is not always 8R exactly.

I just know that when the speaker impedance is low at any particular frequency I have a lot of current to back up the signal...(my opinion on PBTL)

The amp is quiet but the fan needs 50R to slow it down...have same fan in PS and that value worked.

These heatsinks are overkill but that is what I made.

Here is my just completed Class D project

It Uses
- 1.0" LED MP3 Player Audio MP3 Decoder/FM Radio/AUX Board
- SURE Electronics "2 X 25Watt Class D Audio Amplifier Board - TDA7492
- Power Supply via and Old, HP Laptop Supply rated at 18V/5A


I plan on using it in the garage so I can put all my CDs back in the safety of the house... and beat on a USB Stick instead...

On the first run through a set of Technics SB-L31s, it sounds pretty darn good... my only complaint is a bit of digital noise heard between songs when running the USB...

Thanks.

I picked up the MP3 player off Amazon, bit you can find them on EBay, Parts Express, Amazon, etc... It comes with the remote, has a EQ with 6 presets, and works well for the price.

The amp module is from Parts Express. The box came from The Container Store.

Default my ta2024

I have just put the lights in it tonight for added night time listening.

Its based on a Ta2024 module from ebay for 3.88.
For the price I am impressed with it. I have given it a transformer that came out and old slide projector.
The big blue cap came out some scientific gear I was asked to recycle,its a 22.000uf.

I have reused the chassis from a Philips tuner and have used the tuning knob as a volume control.
