If you are talking about chassis' below, they are truly awsome and nice size too (and looking like Madrigal amps). Each is done from 4 sinks I bought years ago at Active Surplus for $10 ea. The heat sinks in front are from R-Theta (in Mississauga), which I also bought years ago, but still available at around $100 ea.
Those chassis' are different from my Aleph 5s which were smaller and in gold. By "the best SS amp out there" I was refering to my previous statement about p2p wired Aleph X from Grey and based on commercial product from Pass Labs.
I figured that since I had so many heat sinks around I might do something useful out of them.😉

ReL R-theta
Do you have the contact info?
hat are the dimensions of those heat sinks in front, they look to be 12" squares that should be about 11.5 pounds each. My guess is a thermal coeffecient of .65, are those fins on .5" spacings? They look to be about 2.33" long, correct.

They look very similar to Aavid part # 65525 in shape, the Aavid part is $80 per foot, but I need to buy 16 feet minimum.

Anthony,
I want to make sure I understand you right. You need 16' yourself (what are you building?) or the minimum quantity that can be ordered is 16'?

The link is http://www.r-theta.com/indexf.html, part #65340, mine are 11" and two of them were perfect for one channel of A75.

Hold off on that purchase 'cuz I just scored (8) 12.125x10.375 heat sinks. They weigh 8.5 lbs. a piece have 32 ridged fins on a 0.375" base and are polished thermalloy. He thinks he has a steady supply for $25 each delivered so I will keep the board posted when I receive the eight coming to me. I like this size because the only finish work required is drilling.

Re: R-theta
Part # 65340 does not come up on the R-Theta site. It just gives me a search error. Is the number correct? Curious the # 65430 comes up on the Aavid site and it is also 11 inches. Is the heat sink form Aavid or R-theta?

Re: R-theta
Nevermind i found it thanks, how did you purchase Hpotter? By foot, by unit, what was ship time? They do small orders? Am I a pest yet? Give me a chance i can try harder! 🙂

I bought my sinks in 1993, paid around $900 for 10pcs. Used 4 of them, still have left 6. I picked them myself from Mississauga location. Recently another member of this Forum bought 4 of them.

posting pcb artwork
Hi,
I've reworked the pcb artwork submitted previously by "tvi". The problem is, I don't know how to attach an image to this forum. For now it's sitting on my Macintosh desktop. My version could use some extra eyes for proofing. The pcb art follows the Aleph concept of placing off board resistors with off board power transistors. The pcb should be flexible enough to accomodate many power output requirements.
Any suggestion are welcome.

Eric,
I've tried uploading a 50K file from my hard drive before ... just like the way you said it ... did not work. I know it's supposed to be something very simple to do but .... John, if it work for you, please let me know how you do it.

Anthony, you really are a "Saint"!
Thanks for the tip. On my Mac the file opened with "simple text" after removing the suffex. It's not very pretty, but I can read the post.
Again, thanks!
