Rhysh,
I am already on the wiki for four boards.
I would be interested in the BOM parts. If they do NOT include the chassis. I have enough aluminum here to build a small jet.

Anyone know of a way to incorporate a servo setup into this build? It could be a rather nice addition. There seems to be enough space if mounted slightly above the board.

Thanks Tad

a couple of empty pads for this sort of optional circuits adds nothing to the cost and adds nothing to the area of the PCB.

Adding multiple pin pitches for all the capacitors allow much more flexibility in cap choice.

Adding pads for test points is also very useful.

rhysh, what heatsinks and caps(40-60K uF) are you going to use, I was planning on using hifi200 as well for cases.. I just sent payment.

I am using the 'Pesante Dissipante' 3u 300m case with inbuilt heatsinks per monoblock. I am using 68,000uf computer grade caps that i happen to have to hand. I will use 2 of these per mononlock.

$ Confirmed.

Is there a certain capacitance for the power supply caps that is suggested? Max-Min?

I am using 2 x 68,000uF per monoblock. That is one cap per rail. I belive alex88 uses 2 x 47,000uF caps per rail. More then 68,000uF is unnecessary, but i belive it will sound diffrent depending how you setup the power supply.

Anyone tried a bank of smaller caps to achieve this capacitance? I understand banks of smaller caps can improve the sound of the midrange and treble.

I would like to try a pair of Avondale Audio
CAP6 modules with my BPA300.

Any thoughts?
