Heatsinks
Does anyone know if a old set of Hafler DH-200 heatsinks will work for this project.
They are 2" high fins, 9 inches long, 4.5 inches high. Smaller surface than the conrad units, but I have them lying around.
Can someone point me to the cooling match these units can get?

Re: Heatsinks
Do you have enough heat sink pieces to run three fets per heat sink? Then it seems perfect.

I received the amp boards today, and again, they shipped me half of what I ordered (50 instead of 100). I suspect that scoring line may have something to do with that😉
So I'm a bit short and people from the end of the ordering list will not receive the boards yet and some will receive partial order only.
The next batch is already ordered and I had hard time sorting the available boards. I'm short of 29 amp boards and 13 PS boards.
If somebody don't need the boards right away, requires less for now or needs them badly, please let me know, and I will try to accomodate your needs.

Peter,
I can give up one of the amp boards I ordered. That would make 1 amp board, and two PS boards for my total order. My intention is to make one dual mono amp.

Hello Peter,
i am probably at the end of your list, but in any case i am not in a hurry, i can wait for the next batch of PCB's.
Ciao,

Peter,
I have 4 amp and 4 psu's on order. I could cut that in half - 2 amp and 2 ps now and wait for the other 2 amp and 2 ps later. I'd like to build up two full stereo amps at this time.
Thanks,
Tom

Peter, I've ordered two psu and two amp sets, I won't be needing them for the forseeable future so I'm happy to cancell my order if it helps your supply chain problem.

Thanks Carpenter,
assuming 6 fets per channel no, I only have two of these. So at best one stereo side. I am just hoping to recycle some hardware and save money here.
I was looking for other alternatives to the Conrads, if there are any URL's abound for them, that would be nice.

Please note that the numbers represent the items that have not been shipped from your original order. They will be shipped as soon as I receive the next batch of boards.
F4 Chassis
Can anyone provide ideas/links for F4 enclosures. A while back someone posted this:
http://www.atiresearch-anodized.com/ATI-639M.html
Looks good but there were no responses regarding the possible suitability of the heatsinks. Any thoughts/suggestions?

Re: F4 Chassis
162.56 h (6.4") X 596.90 d (23.5") seems to be the size of the heatsinks. The fins appear to be 25mm (1.0"). Going on gut, it may work, but I'd rather see the fins protruding a bit longer for some breathing room. The chassis is probably quite spendy. You might be better off purchasing a bare chassis, adding heat sinks to the sides and designing your own face plate.

Chassis
Carpenter,
I plan on using the Conrad Heatsinks, but am wondering if others could post some other workable options.
You mention chassis,
Any vendors you or anyone else can recommend to buy?
I looked at the above mentioned chassis, shipping from Overseas to USA is at least 150 on the slow boat, and it's a 300-350 dollar US chassis.
I think I will work with local CNC people first, if there isn't another common chassis to be recommended for F1-F4 clones for breathing room.

You don't really need a coventional chassis with those amps, something like that will work really well too: http://www.diyaudio.com/forums/showthread.php?postid=1254948#post1254948
Peter,
If you ever decide to put together chassis kits for the F4 I'd be more than interested in buying a couple from you! But to be honest I'm not sure how I'd manage to put together something like your creations in my apartment without making an utter mess...
cheers.

The utter mess part is the best part. You should have seen my apartment when I was assembling my line arrays in th living room. 24 6.5" drivers. It was a horror show. I lived in chaos for about a week. It was well worth it.
