Getting the famous MF30 heatsink?

[dantwomey]

This question can have multiple titles?

Where can you obtain the now famous Aleph 5 MF30 heatsink?

Is there a reasonable facsimile out there?

Other heatsinks used?

Suggextions, links, part no.'s?

I don't know if those are the sinks you were asking about, but they look pretty close to the ones used originally on Aleph 0 and subsequent Alephs. Later different sinks were used, but I always thought that those looked better.

I found them in an old Ahamtor catalog. The phone listed in catalog is 1-800-367-7588. Looks like another Diyaudio mystery solved.

Actually, I was trying to duplicate Mark Finnis's (http://www.users.bigpond.net.au/mefi...nstruction.htm) Aleph 5. That's why I'm pursuing the exact same heatsinks that he used. If you look at his site you'll see that the heat sink's he used you'll see they have a unique feature. They have two bars perpendicular to the base where the transistors attach. Here's a pic:

Check the Trading Post, someone in States was selling them.

rlim was selling some as a one time deal in the trading post (I got a few), but the deal's over. He might have some insight on getting them shipped from Aus however.

Are these sinks (one of them) enough for an Aleph5 (one channel)? I know Mark Finnis built a stereo A5 with a pair, but he never answered any of the questions regarding temperature in another thread. They seem about the same size as the sinks on the Aleph 60 (actually a little shorter), but the 60 was a monoblock if I'm not mistaken. Makes me worry. I'll probably proceed with an Aleph 30 until then (or something scaled in between).

They are nice sinks (appearance anyway.)

I believe MFinnis mentioned in his article that these sinks were "right at the limit" or words to that effect when used one per channel on an Aleph 5.

I will be using 3 of them on my Aleph 5, ThingyNess has the vendor info. for aquiring them.

I can tell you though that they are beautiful sinks and an excellent value.

Peter Daniel - I'm from Europe - so the phone number doesn't help me much - but I'm very interested about that heatsinks - the cube design is my favourite since I first some one of the Aleph's ... Any sugestions how to get some more infos about that heatsinks - particullary the price, availability, ...

Thanks in advance

Peter! Because you are both a fellow canuck and a fellow Torontonian I was hoping you could point me in the direction of some heatsink suppliers in our area.

I believe the heatsink is produced by Conrad Engineering. You should be able to order it through Printed Electronics, they sell internationally. Sales Enquiries: pcbs@alphalink.com.au.

Hope that helps.

Cheers,

Pete
