#Aer domino amp plus#

In the Domino amp the heat sink is alloy and has no forced draft cooling so the heat dissipation characteristic is much lower.Ī major reason why this amp decided to self destruct was a result of the heat sink integrity.

This why the Marshall AVT150 has the same two chips rated at 150watts rms and the Domino is rated at 50 watts lower.

The difference in design is not great, the major difference being that in the Marshall amps the chips are built on a separate pcb and is fan cooled which is a big plus in getting rid of heat. The AVT 150 uses two of these in bridge mode, which is something I should cover as we go on. These are exactly the same chips as are used in the Marshall AVT series amps. The property that limits the output of these chips (and also causes them the most problems, often) is how fast they can get rid of the heat that is developed in pushing out power to the load (speakers). Each device is rated at 100 watts rms dissipation, so should, on the face of it, be good for 200 watts all told. These two little black blobs are TDA7294 integrated circuits (chips), and these are the devices that make this little AER amp make sound. It has to be said that this amp was devastatingly silent in operation.That’s because it didn’t work at all. Because they might just sus out that these designs are not particularly clever, nor are they especially well manufactured, nor do they work all that brilliantly well. This could also mean, possibly, that it would be unwise for them to let anybody in there who might know what they’re doing. This means that their designs are so clever that nobody else should be allowed to repair them. Un….fortunately….we have yet another example of a company on the Unofficial Secrets list.
