Conrad heatsinks group buy

cwujek · 12th February 2008, 06:55 AM

Getting ready to build a monster class A amplifier, and will be needing some large heatsinks. I've seen the group buy for Conrad heat sinks awhile ago, I think it's about time for another. Goal is going to be 50 pieces, which shouldn't be too hard. I will be ordering six for myself. What heat sink would people be the most interested in? I'm thinking the MF30-100 is sufficient for my needs, and it's a nice size too. Fins are 1.81 inches tall (46mm), and the base dimensions are 3.94 inches (100mm) by 11.81 inches (300mm). Fins are oriented vertically for best heat dissipation. Still waiting for a response from Conrad regarding the cost of 50+ heatsinks, I've emailed them three times in the last month with no response, I'm guessing the online inquiry form is not working... Just getting this out there to see the interest. Here's a link for more info and a pictures:

Just some info

I have earlier bought a bunch of sinks from Conrad, and have always received fast replies and deliveries.

Try email them at: sales (at) conradheatsinks *dot* com

Yeah, I sent an email yesterday to this address, so hopefully I will hear back soon with prices. Thanks,

Hi cwujek,

If no joy is had, Altronics do mail order and stock that heatsink. Another Australian company like Conrad. They supply manufacturers as well so should be OK with bulk orders.

I'd probably be interested in a pair of those.

jackh · 19th February 2008, 12:22 AM

I'd be interested in 4 of the heat sinks

Still waiting for a response from Conrad. I've tried multiple ways to contact them, and cannot get a response. Anyone in Australia want to give them a ring to see what's up?

I've bought heatsinks from Conrad, and they are very high quality.

For class A I'd strongly recommend the MF35-151.5. When corrected for ambient room temperature, this model has a c/w rating of .29.

It's much better to call Conrad rather than email.

BTW, one pair of MF35-151.5's is design perfect for a stereo Aleph30. Mine runs about 145 degrees F after 2 hours.

I would be interested in some MF35-151.5...

cwujek · 21st February 2008, 12:19 AM

I requested a quote of a few different models. The MF35-151.5 was one of them (although I don't like the 151.5mm height vs the 100mm height). Conrad actually is having email problems, and they sent me a letter explaining the situation via Airmail (now that's good customer service!). It seems that my email is the only one with this problem. So I have created a new email with a different server, and hopefully will have a quote soon. Thanks for you patience, there already is enough interest (on this forum and elsewhere) to justify ordering.
