In Reply to: Can an amp have too much heatsink? posted by tweakk on February 2, 2010 at 05:49:19:
Most power amp chips run very little idle current through them. So, at idle they need very little heatsink. If you are constantly playing them loud, near their limit then some more serious heatsinking may be required. Generally, you can just mount them to the side of an alluminum chassis of on a small heatsink. Larger heatsinks will not hurt, but be sure to damp any heatsinks you use (sounds better). If you run your fingernail along the ribs of the heatsink and it makes metalic sounds then those sounds will be tranfered through the device and be "heard" through your speakers. A single piece of constrained layer damping material along the ribs edge is all you need to damp them.....then, when you run your fingernail along the edges it makes a very damped sound with no ringing. The sound is sweeter....less "transistory".....he he. Try it!
