Hi Everyone,
I have found a heat sink distributor for Seifert extrusion number KL-271:
With the fins oriented vertically, this heatsink measures 12" wide, 8" long, 3.25" thick, and has a 1/2" thick back plate. A singe 8" (200mm) length of this heat sink with black anodize and natural convection is rated for 0.18c/w
or approximately 140-150
watts dissipation with a 25c temperature rise.
One of these would comfortably run a stereo Mini-Aleph. Two of these sinks would provide 0.09c/w of cooling that can dissipate approximately 280-300 watts and should be sufficient for a 100wpc Aleph-X monoblock or even an Aleph 2 monoblock.
The distributor has a minimum order of 10 pieces, which is more than most people might want, so I have inquired about the possiblity of a group purchase and different quantities and price points.
To give you an idea of cost, the unit price for 10 of these heatsinks is approx $60 each (not including shipping).
I will be able to provide more details shortly...
Any interest?? I will post more details shortly, and if there is sufficient interest, I'll set up a wiki...
