I found out that tubes and car audio are not match made in heaven. If you put tubes inside car, in a few months the particles inside the tube (I don't know which one) is falling apart. It can be heard if you shake the tubes, something is falling inside the tube. The bigger the tube, the worse it will be.

So you'd ideally mount the valve chassis on anti-vibration mounts. Quite a few valves give figures for the acceleration/vibration that they will withstand. Remember that valves were used in WWII bombers (probably not terribly quiet) and as proximity fuzes in shells (yes, fired out of a gun!).
But you haven't answered the original question: Why call this thread valveaudio when there isn't a valve in sight?
It's like this. In here (not familiar with British English), the word "Valve" is associated with valve as water-valve. Later I found out that in British English, Valve equals Tubes.
The first thing I learn about transistor (from my uncle) is that transistor works like water-valve, you can put out little water or heavy water just by steering the valve. Transistor do the same as water-valve does, only transistor do it with electricity. I won't forget this simple principle, so I use word Valveaudio (not related with tubes, but with how 1 transistor works in controlling current flow).

I have had tube amps in vehicle for over two years with out any problems...and were are talking an airbag suspension which isn't the greatest..not a single problem...though I'm not using them now "went to sinfoni" I have never exp nor have anybody else with the same amps with the problems you have discribed...
by the way...amps look great!!

Hi, Trusound,
Yes, there are several tricks to make tubes works in car environment. Something like picking up tube types (that stands vibrations), not using socket (solder directly to PCB), using tubes in special way (low voltage, advoiding high voltage), etc. These ways will make tubes can work in car audio.

Then the designer is a good one 
He can pick components and topology that suites the need best. There are some major brands that successfull in making full tubes-high voltage car amps. You can guess yourself what brand.
Tube socket is one of weakness for tubes in car. They can contribute strange noise (while the amp and the tubes itself are OK), because of scales inside the sockets.

Mentioning Sinfoni. My workshop here is appointed by the official importir here to modify/upgrade Sinfoni's. Just arrived the black 100.2SPX to be modified by Valveaudio

sweet!!!!
looks like your playing with the shadow edition...very sweet..may I ask what you are doing to them?
here are mine

Hi, Trusound,
I hope there's no Sinfoni designer here
To be simple : Sinfoni power amps have some intermodulation. Making it having much less intermodulation will sound much-much-much-much-much-much......better......
Looking at your photograph, do you have share in Sinfoni company? How come you got so much of them ?
