Kevin's orginal design shows half the output devices. Does leaving half the output devices unpopulated change the sound quality of the amp if driving any normal headphone short of a K-1000 ?

For a qty of 1, it was $75 shipped, I think. Obviously, we can get a better break if we buy in larger qty.

Here is what my Dynamite heatsinks look like. Drilling all the holes to the precision required to mount the fabricated heatsink was not easy.

Group Build: Dynafet
I thought it was about half of the Dynahi. If so, I have internal heatsinks in the 12"x12"x3" Par-metal case for my Dynamite and they work just fine. Of course those heatsinks were labor intensive to build and mount to the dynahi boards.

So these little heat sinks would be attached to the output devices, and then what... to some larger heatsink on the side of the case. What about a 2 chassis option: one for the psu's and one for the amp boards. The case I just got from Par Metals was very nice, .18" brushed aluminum face plate, with black painted body, countersunk stainless screws.

Group Build: Dynafet
luvdunhill, I've lost track of the board configuration for the DynaFet, can you post a pic and some dimensions? What about PSU? I would be willing to get in on a 4-ch for myself and build a couple of 4-ch for others. By build, are we talking just the pcb's or entire amps?? What would be the heatsinking configuration for the output drivers? Holes placement identical to the Dynahi boards would be nice, or onboard heatsinks ala beta22 is handy. Cheers Pete
