ELTIM PA-3886, 80W Amplifier modules

More than once we are asked to develop an ELTIM way built amplifier module based on the very nice performing / cost effective LM3886 IC from Texas Instruments.
More and more experience that the cheap crap one can find all over the internet have way to small tracks, poor parts, etc. resulting in a dissapointing sound quality and a short life cycle.
So, as you can read below, we finally did. Now you can build a cost effective, quality and long lasting amplifier yourself. We made it a double sided, 2x35um layer, EU manufactured board, assisted quality components. This means that now the IC (original TI, with metal back plate) can be used at full, resulting in a max. output of 80W. Especially the versions with integrates, symmetrical power supply are interesting. With those, you only need to connect a transformer.

These modules are a nice starter project and/or for those who need only medium (80W/8ohms) power with mono modules.
It is also very easy to build multichannel systems with these modules by a clever sandwich construction, as a pack mounted to a large heatsink.
