Just out of curiousity, why do residents of Canada outside your province need to pay 13% instead of just GST? If it is because they ship to you and then you ship to us, maybe we should get them shipped out of Ontario first and then distribute them just on principle alone. I hate paying tax when I don't need to and in Alberta we don't need to pay PST.

All the sheet metal is purchased locally and taken to the refinishers by me and then shipped by me, hence you pay all taxes.. sorry.

The Heatsinks are considered a consolidated order, if you want to save the taxes then you will have to pay courier shipping rates. R-Theta does not ship via CanadaPost. To get the best price for everyone I have comitted to one Canadian shipping point and one US shipping point. The orders are all individually packaged and labeled by R-Theta as I provide them a shipping manifest so I just take them to the post office and mail them. This year I will be using your Paypal payments to generate an E-Post label with Canada Post through Pay Pal.

I beleive you can claim the taxes back from out of province purchases, can you not?

Re: Large Chassis

dcbingaman said:
Hi, Anthony - the large design looks pretty good for an F5 stereo or bridged monoblock amp also. Have you looked at the extrusions that his guy is selling - http://www.heatsinkusa.com/. These are 8.5" wide and can be cut to any length you want. I calculated their thermal resistance vs. length at three temperatures - see attached. One pair at 10" length would work for an F4 or F5 stereo or bridged / monoblock. Anyway I'm in for three "basic" chassis', (I've got a good drill press so holes don't scare me), if you can pull in enough orders.

Hello, you need to update the wiki, if you want 3 large Chassis you would need 12 heatsinks not 3.

large Chassis requires 4 per and small 2 per. The pricing is for each heatsink.

Thanks

I have added an update for March 9th and added the pricing for the profile configurations. Pricing now based on MOQ of 100 heatsinks.

R-Theta GB

We are getting a pretty good picture of what our little GB is going to look like, it would be nice if we could stir up some general interest on the board. I have posted the pricing at 100 units, now to hit this number we have to all agree to the same profile, majority rules.

So as far as the votes so far, 1 Member - 1 Vote, it is the fairest way so everyone gets a say in the matter.

Heatsink choice so far is a tie between 10" Basic and 10" with holes @ 6 ea.

There is enough Chassis interest to accomodate both.

With only 5 votes for the FPE Rear panel, this one is not looking good, minimum is 20 to get this option going.

Chassis anodizing is overwhelming in agreement, I can probably accomodate the two members who would rather opt out.

I need a few more votes on the heavier top cover to make that viable.

Heatsink Anodizing, if the order is large enough R-Theta will let us run both clear and black on the same order with no additional setup charge.

Anthony

P.S. These numbers could change quickly if Icarium brings in his goup buy.

Anthony,

I'm building an F5 (albeit slowly), but the large chassis will likely best fit my needs. Even better if all is drilled and prepped for quick assembly.

So far, your GB seems to be my best hope for keeping cost down and assembly the easiest.

When I have a chance, I will post to the wiki.

Anthony,

Please clear up my understanding of drilling & tapping heatsinks & panels. 😕

As I understand it, the panels (T-B-F-B) will attach directly to the HSs?
i.e. not via added channels/bars. 😀

Altho, how will the HSs, two per side, be joined? 🙄

Thanks,

Chassi F3 and F5

I put my self on the wiki but I'm still confused I want to build an F3 then an F5 and thought this would be chance to get both chassis.

I put two large but think I might be able to go with small for the F3 plus I'm confused by the last post do I need 4 sinks for the large

Anthony,

Also, I'm guessing Chassis (large) in the wiki means four sinks, two per side.
As opposed to Chassis (small) one sink per side??

Hello Ichiban, it looks like gjorgji posted a reply for you.

To close the loop on your question, yes 2 heatsinks form the sides of a small chassis and 4 heatsinks form the side of a large chassis.

As the heatsinks are 6.95" wide we will be setting them side by side and strapping them together with an upper and lower horizontal brace.

The front and Back panel serve as torsional reinforcement (like a cross brace). The way we achieve this is by using the 7" or 8" L channel and four mounting points on the front and back panel.

The bottom panel will bolt up to the underside of the bottom rail, (6 to 8 mounting points recommended)

The top panel lies on top of the top rail and only 4 points are required.

The braces are purely for mechanical assembly and the heatsinks, although clamped tightly together, are still 4 seperate thermal entities. This means that any heat sources should be balanced evenly on each of the four heatsinks. (Large Chassis)

The Small Chassis will assemble in an identical fashion except the horizontal rails will only serve to hold the 4 panels together in structural unity as there is only 2 heatsinks.
