Wiki Updated

March 29th 2009

I have added a preliminary accounting sheet for financial transactions, this is not active as yet and will become active when I close the Initial Interest portion of this GB April 19th 2009

As there is a large US contingent in the GB, I am looking for a Member to act as a central delivery hub close to Southern Ontario, Canada. This member would need adequate space to recieve a skid of Heatsinks and have his own transportation with easy access to postal facilities. As was the case in the last GB all the boxes are prepackaged and labeled and only need to be mailed. I will transfer the funds to the US member to pay for USPS fees, as I will be the central point for collecting funds. The advantage to US members is the tax savings, (13%) as R-Theta will have a consolidated US shipment. I beleive the shipping will be cheaper from within the continental US and all customs and brokerage fees are included in one consolidated shipment and shared equally amoungst all US members.

The designated US Member must be of good standing and have the support of the group as there is an enormous amount of trust and responsibility required of this individual

I'm definitely interested in one case kit. I'd prefer clear heat sinks with everything else black.

And probably some extra heat sinks too.

I'm new to the 'wiki' think - I'm going to try to add to it - hopefully I won't mess it up.

QUESTION: when I add to the wiki, am I supposed to update the totals, or does someone else do that???

Hello Sandbasser, If you want the Chassis Kit all black then you will need to add the Anodize option. Other than that your choices seem pretty clear to me, you want to build a large chassis and buy some extra "Small heatsinks".

Updated the wiki - added anodizing option (I hope) 🙂

Still considering back panel and parts, will decide NLT tomorrow afternoon.

Thanks,

I was recently asked by a member if this GB would be good for anf F4, I created this thermal plot for him and thought I would share it.

You must use 3 devices per section, two sections per channel. So a stereo F4 would be 4 x 6" 9013 and a small chassis kit.

I have used 12 watts per device for the F4, based on 22volts and .53A bias.

Anthony,

Not sure in what state are we now. Are you ready to collect money? I'll like to see this sooner if possible. I might start GB for hifi2000 once this is closed.

I will sum up what we have and post the final dollars by member shortly before April 19th. There are usually a few members who drop out at that point as the dollars add up. A few days after that I will ask for funds, this is always the critical stage as members who run a GB should not actually engage a supplier until they have funds on hand.

Regards

Anthony

PS. What is a HiFi2000?

I am not sure If I mentioned this or not, I will be pre drilling & countersinking where appropriate, the holes in the anodized parts. Actually the Back, Top and Front, there are too many variations on the bottom panel to drill all the holes in it. I will drill the 8 basic mounting holes in the bottom plates before anodizing. I could possibly drill the holes for the feet as thier position is unlikely to cause controversy. They could be sized for a 10/32 UNF tap, so members only have to Tap a thread.

I am contemplating predrilling the internal frame components as well, again tapping for the plate mounting points would be up to the individual members.

Where the frame bolts to the heatsinks the holes are clearance holes and are not tapped. Where the plates bolt to the frame, those holes need to be tapped. As the front plate is blind mounted the Front rails will have clearance holes and the Front plate will need to be bottom tapped for #10/32 screws (4).

The tapping list is as follows:
6 to 8 #10 on the bottom rails
4 #8 on the top rails
4 #8 on the back rails
4 #10 on the back side of the Front Plate

Remember Members are responsible for drilling and tapping the Device and PCB mounting holes in the heatsink itself. They are predrilled and tapped for frame rails only.

ok, I'm finally getting this figured out for my project. I do have a question about this statement:

"If we get the chassis Anodized Black and the heatsinks Anodize Black it is going to look very dark. The option would be to leave the front plate out of the Anodizing batch and members can finish to thier own preference, or get the heatsinks Clear Anodized."

What are the anodizing options for the chassis parts? Clear only? Once I figure this out, I'll add my order.

Also, will the 0.125" cover option be flush with the top of the heat sinks?
