Hi,
Here is my Velleman K4040 kit ready for final bias adjustment. :)
It took me a weekend or about 15 hours to put her together. Easy kit to build with nice finish in black and chrome.

An externally hosted image should be here but it was not working when we last tested it.


I’ve got the work log here http://www.veiset.net/k4040/k4040wl01.html (in Norwegian only, but the pictures tells the story)

The new look of my KT88 SE amp

¿Remember the amp I did in a chassis made with recycled parts taken from the bin?: link here

Now I have mounted it in a standard 1U rack box.

The KT88 is runing in triode mode. I love the sound! :)

What is it with you Canadians and moving parts... ;)

I met a Canadian DIYer from Quebec? (I forget) a couple of years ago at one of those audio shows in NYC. He brought down his turntable he had made to use as a source for one of the rooms. The turntable was machined in aluminum with carbon fiber throughout; plith, platter, arm... The turntable was isolated by some form of liquid damping at the four corners.

It was the most beautiful turntable I had ever seen. And unique...the only one made.

Although form must follow function; no DIYer should be afraid of making something too beautiful. :angel:

Maybe it looks like this.

Hi Everynone! My first post at this interesting forum.

I could start with following suit - showing off some of the hardware I have build:

First a pre-amp using ECC82

Next out is a OTL headphone amp based on 6SN7
