100W Ultimate Fidelity Amplifier


Yes,that really is a great pcb indeed. It is just the fact that i have drawn my pcb such a way that is suitable for my heatsinks,and it has three pairs of output transistors and Power-Signal-Clip indication on it.
But,pcb from your link is really really nice one,no question about that!
 
I was thinking of a stereo amp for Apex FH-9 xrk mod, still a work in progress to achieve symmetry and get proper grounding. . i have a 90mm x 290mm heaksink salvaged from an onkyo receiver.

Here are final files and gerbers

Thanks,
these are stereo boards, no need to cut in half.
Simple salvaged MS chassis of an old 5.1 receiver would do perfectly.
I even plan to use the heatsink from the old receiver.

you can even plan for pesante 3U kind of chassis which is cheaper compared to dissipante. Pesante 3U – diyAudio Store
if you have a single heatsink of 100mm height, you can mount it inside the case near the holes/slots for heat dissipation.
