Thanks for the compliment.
It is still, by my own standard, a case which was designed to a budget.
So I did not have all design freedom as I wanted (e.g. a even more sculptured front panel).

This is a very nice case.
How does sculpturing the front panel increase the cost, is it time and labour that adds to it, or just time on the CNC machine?
It’s so minimalistic, maybe too sparse then again maybe not, it’s certainly elegantly understated, all of which doesn’t really surprise me from what little I know of Patricks taste.
It’s an absolute triumph, I had no doubt that this case was going to be very tastefully designed, my expectations have been blown away.

The trick is not in the amount of visual features, but in the exact proportions that makes it visually appealing, to me at least.
But such kind words from a professional designer is some compliment.

> I noticed that there's no rca connection and the power socket is not of the normal 3-pin type.
If you have read all my posts about the balanced F5X, then you should know that a balanced input is a must. Hence no RCA.
The normal IEC 3-pin connector is too large to fit. The one shown here is Neutrik PowerCon. Widely available and typical Swiss quality.

Attached the provisional schematics for the PSU, thanks to Mark Lai.
Only details of one channel shown.

Great work Patrick. I am definitely impressed!
I love the modularity of the case, and the ability to assemble and test large portions of the amplifier with ease. Being an engineer who deals with vibrational issues in buildings, I really like your vibration damping scheme for the transformers. Overall, its a extremely well thought out and visually clean looking design. Only thing its missing is some sort of cool F5X logo... =)

We had a logo, but the forum was against putting it on the case.
And it will add some costs, since it requires the use of a high speed spindle to CNC mill 1mm curvy slots.
Maybe we'll reconsider if the majority wants it.

nice work Patrick, i wonder, would it be possible to buy without the heatsinks? this will add considerably to the international shipping cost and i can just get them locally. without them i'm sure it could be shipped flatpack. i actually already have some, although i suppose getting them machined for the fixtures ,would eat that up. just feels wrong getting them shipped all the way over there and then back again.
i really like the detail of the underside from an engineering point of view and its a pity only i'll know its there. so the rear will or can be shipped blank? i wont be using any of those connectors except for the powercon.

Please be patient and wait for details as these are still being sorted.
I know it does not make sense to ship Conrads to USA and then back to Australia.

You may, if you wish, consider. putting your name on the reserve list at the GB thread.
I expect a few people to opt out eventually.
And we'll try our very best to accommodate as many as we possibly can.

We have now put together a team to organise the GB for the case and main heat sinks.
The GB leader will be johnwmclean.
Details are still being worked out as to who does what, etc.
We shall announce details, including price and options, towards end of the week.
We also have 2 volunteers to match the 1000 MPC74 resistors.
Again a team will organise the GB. The leader will be Horio.
We are looking for 3 additional volunteers to act as regional distributors, one for North America, one for Europe, one for Asia / Australia / ....
For simplicity, resistors will only be available in sets of 8, matched to well below 1%, most probably 0.2%.
(which will be limited by the Fluke multimeters used for matching).
We shall charge 8USD per set of 8 matched resistors (so 1USD per resistor), and donate all "profits" to the Fukushima Earth Quake victims.
My most sincere thanks to Horio and flg for volunteering to do the donkey work.
Matching 500 resistors and sorting them into sets is really hard work.
Anyone would like to help out with distribution of the resistors (and collect money, addresses, .... quite a bit of work involved) ?
