you can ask Toroidy for either interwinding screen or external gauss band.
or both.
The interwinding screen takes primary interference to chassis/enclosure and NEEDs a connection wire to the chassis.
The external gauss band does not have any wire connection.

 

[diyralf]

Yep, on one photo you can see a green yellow 0-wire. I'm just wondering if the resin is necessary. Are there less vibrations to hear?

 

[astx]

Resin reduces the mechanical hum and is extra isolation safety.

some extra delay ... floor isn't dry enough to put parquet on it.
Testing cinema screen.

Some short side question: Does Toroidy.pl als have experience in winding toroidal output transformers for tube amplifiers?


Best regards!

I don't exactly know where you're living, Tony, but at least the actual weather here really isn't dedicated for accelerated masonry drying;-).


Btw, great job! I envy you for this AV room!


Best regards!

Wonderful built!

Thanks Kay and Thimios!

Living somewhere in tyrol ...

BTW: the weather isn't so bad for drying - the air is cold and dry.
Several times a day I open the windows for air exchange.
The room is heated and I'm using a dehumidifier (TTK 127 E, Trotek) - the partially higher thickness (~ 7-8 cm) of the anhydrit floor needs extra drying time ...

 

[Kay Pirinha]

...and surely increases your power bill significantly :eek!:!


Best regards!

Merry christmas to all DIYers.

Best regards, Toni

Same to all
Got to like that you are hanging art before base board/trim is done.
I like the reflected light, colour temp could be lower imo
Raised floor for wiring etc. good job, enjoy

Cheers

Yes - 4000k. Have used newest LED stripes with Ra > 95.
The decision to use nearly daylight temperature for left and right sided LED stripes (diy) was to be able to see the correct colors of art and parts.
Each of the 4 LED lights has ~ 3000 lumen so my old eyes can see better.

I have additional warm light sources for audio listening only.

Luckily I bought several hundred Wolfram / Edison lamps for reserve.

800W versus 156W for same lumen ...
The diy aluminium led stripe keeps the leds very cool to (hopefully) increase their lifetime.
Warm white for relaxed audio listening or television viewing will be produced by dimmable 20W halogen lamps. Still available parts.

We have nuclear power plants ;-)

I use filament LED only in my house. Looks almost same as the old bulbs, but it save lot of energy...

You're living next to Fukushima or in Pribyat?

Happy new year to all DIYers!

Home cinema mostly finished. Need some good placed bass traps, diffusors and absorbers to optimize the sound. Denon's build in soundcorrection DSP helps for now ...

Next step: relocating the lab to be able to finish the SA2017 4 channel IXYS VMOS.
