Wow, you got that quick. They ship that to you direct from China? I was browsing around their website and they make some nice looking racks.

It is a VERY nice looking rack indeed.

But for those who want to make the most of the vibration isolation function of the transformer cradle, both the amp and the cradle has to sit on the ground, or at least a flat piece of plate which is 2x as heavy as the amp and of a very high stiffness. EXample would be a thick piece of granite. It is basic mechanical engineering. No other way round I am afraid.

But of course you do not have to use that function, and can just bolt the cradle tight to the case.

The promised circuit description of the protection board :

http://www.xen-audio.com/documents/f...20Chpt%201.pdf

Chapter 2 which is assembly & test is to follow.
This is delayed somewhat as Alexis has yet another hard disk failure.
So he lost a few days' work.

Ashaw ,

Been four months since I made the payment but two F5X protection kits have not reached me. Can you please give me the tracking number of the package? Or any other information about sending the package.

Thank you.

I just emailed him to give you an answer at the GB thread.
I am sure it will be resolved eventually. Alexis is not here to cheat.
If anything perhaps a bit unorganised ......

I am quite sad to hear that you have had problems. You and alazeira (I hope I spelled that right) have seemed to have a problem with the package being sent. As your package was sent by regular mail plus postal insurance I do not have a tracing number, I have got in my files lodgement stubs which I am going to use to try to claim insurance the moment I can open the box that contains them (I just moved again). I have most of enough parts here on my desk waiting to resend both your orders. By way of compensation If you would like I will solder one board each here and test it for you, with the modifications already done, and use this task to make an instructional video for all the rest. Otherwise I can send them as is and wait a little time myself. I will send this by courier at my expense, however it will take me about 1 week to solder and test them. Would you find this acceptable.

I am happy to give you my final PCBs as a part of this at no cost to you, if I need more I will do a small run myself.

P.s I know that you ordered two kits and will of course send you annoy her kit with the completed board, also I will send you two free LEDs on top of those in the kit as these are the hardest parts to obtain and you may find them useful as spares.

Sorry for all these problems and thank you for your understanding.
Ashaw, your offer is acceptable for me, thanks.
I'll wait.

Great NIc,

Two questions
1 ...what temp at sinks outer and inner ? because it looks like air flow from below amp will be scarse with solid glass so close to bottom.
2 ...how much was it delivered to your door ?

I had it running for > 3 hours yesterday evening and the rack does not make the amp run any hotter. Surprisingly the (1.2 cm thick) glass shelves do not heat up noticeably despite the quite intense heat rising from the resistors in the CRC. The way Patrick and co. constructed the amp it basically works like a chimney where convection will draw in fresh air from the buttom. Having a large smooth surface below the amp will only improve this - I think.
The rack is distributed in Italy (and other EU countries) by Azimut Audio.
