Is there anything in North America that is simple like Conrad Heatskinks?

Thanks. :0005:

Not that I know of, I bit the bullet and paid the shipping for a few of the flanged heatsinks that looked perfect for a headphone amp I was building. They are heavy and nicely machined it seems.

Hi, Yep. That fits the bill. I think they need a $125.00 minimum order, though. :?

Hey ozone,
Long time no see... :mrgreen: (we just met 1 hour ago)
Here you have the two links:
1. Closer than Oz
2. Really close

and then there's that surplus store in Laval, sometimes they bring in nice chunks for just a few pennies...I'd start hunting there first...

I just ordered from this place. The service was great and prices fine. They specialize in heavy weight heatsinks. What I received was in perfect shape, cut exactly as I specified and shipped fast.

What did you get, and how much was it? The aavids look like pretty serious sinks.

I got 4 pieces of Aavid 61570 8" long for $ 40 each. My problem was that I already had 8 pieces of that heat sink and I needed 4 more of the same. First I made a search and I only found a places that require to by 16 ft for $ 70 per foot as minimum. I tried to organize a group buy but that didn't go well. I asked the guy who sold me his sinks where he got them but no answers from him. So finally I found this place and I got exactly the same ones that I was looking. It turns out that it was the same place where my original seller got his shipment from.

No, not at all. Just there is only 24 hours in one day. When you see the project, that I am working on, finished you will understand. I have all my time devoted to this big X350/600/1000 amp. I started this about two months ago and I am still working on the cases. I have electronics ready and it is all machining time. The size of the case is 15" x 11" x 21"
(38.1 x 28 x 53cm) with 6 of above mentioned heatsinks. There are two cases as amps are going to be monoblocks. Body is made off 0.4" (10mm) aluminum and the front plate is 0.5" (12.7 mm) aluminum. I am doing all machining and lathe work, as well as powder coating. Here is the drawing just to get the idea. I am planning this to be my last amp that I am making as it will do everything that Aleph 30 doesn't. So between Aleph 30, this Aleph X and my tubes I will be set.
Project that we spoke about is still in my head and I am thinking exactly what I need to do about. Once I get everything sorted out than I will go ahaid with clear idea on dimensions, concept... Problem is that I have that assembled and working, so I have to pull it apart and start over. 6 channel ballanced volume control and separate X Bosoz preamps = a lots of wires and connectors (I hate these)... So, no changes in my plans just do not want to go forward yet without me first sorting out. Thank you very much for your help.

Thank you.
Coming from you is a real compliment.
I am making pictures as I go, so I am planning to make it as a building manual. I hope it will help someone who is thinking how to do it. It will cover aluminum cutting, milling, drilling, tapping, and finish - powder coating. As you know case is by far bigger job than electronics.
Peace
