Default Aleph 2 Heat Sink (chassis)

Hi all,
I am planning to build one of Mr. Pass design which is Aleph 2. The main problem that I have is obtaining heatsink for the amp. I am having a very hard time to obtain the heat sink locally (Jakarta, Indonesia), of course, I can always order it from abroad, but it would be very expensive. Luckily, after searching extensively, I found heatsinks that I think will fit for the aleph 2. The size of each heatsink is 200mm Length, 84mm Width and 81.5mm tall. I am planning to put about 6 of it vertically and joint the by L shape alumunium bar for each side of the chassis. THe cover will be brush and anodized aluminum sheet. Will the heatsink be adequate for this amp?

You NEED to tell us where you get those and how much!! Is that cut to custom length?

Did you say you're going to use 12 of that for each monoblock?!

I bought it locally in Jakarta, Indonesia. It cost $9.50 for each block. Yes, I am planning to use 5 or 6 block for ach side of the chassis for a total of 10 or 12 block for each mono block. I am planning to buy some more after I got some comment from the elder in this forum. . BTW, how many uF is needed for the PS of EACH monoblock? I just purchased ELNA Audio grade 10000uf 56VDC and wandering if I can use it. Thank you for all the help and comment.

If it's $9.50 per piece in Indonesian money .... that's may be US$1.00 per piece (I don't really know the conversion rate)? Please check it out for us ... quantity in stock, pricing in US$ & if they can do international shipping. I will definitely buy a batch of them ... even if I don't need it.
