Thanks for the helps.
BTW, I read about your threads about dual mono above.
I am sourcing for chassis.
I just wonder if the PSU (Toroid transfo + 16 huge caps) is taken out to a short chassis and leaving all Stereo parts ( inputs & outputs ) in a 17" X 16" X 6" (high ) chassis with the mosfets mounted to the sinks with fins as 2 walls on 2 sides . With the big empty space in the center releases much of the demanding heat sink to 2 moderate sink of 16" X 6" X 1.5" (fin) ?
You know I am a newbie, just curious would it work for at least v2 with 32V rail (or v3 ) .

hello. if you have a well vented chassis. and +/-32V 4 pair of output fets.
say you bias it at 1.6A . 32x1.6x2=103W pr ch. (40WclassA in 8ohm)
then the 4U400mm(modushop) chassis will be perfect. or if you like to build chassis.
then heatsinksUSA's 10.08" profiles 6" are great. 2 pr side. they can do 130W+ pr side if the outputs are well spaced🙂
 
Thanks. I figure to use Dual PSU in a ~ 4" high chassis to give 2 X 500W toroidal power house feeding the vented but no fan 4 pairs FET Amp F5 Turbo circuits.
The rectifying cost is mainly the 12 cap anyway and price of 800W toroid may be doubled that of 500W's. In contrast to 2 muscular 10" monoblock chassis building, this alternative approach save some steel for military tanks production

So we know we need about 2 six inch heatsinks 12 inches wide with 2 inch fins (HEATSINK USA).
if we used one common sink for cooling the diodes, how large would that be? Could you think of a configuration to have that third heatsink as the front or back panel of the enclosure?
I still like the idea of one enclosure for stereo, but im not sure how to make that work....
Thanks for answering my questions..
