AN DAC Kit arrived

It arrived. Yes... after a month of waiting it finally did.

Here are some of pictures (package and a building process) with comments.

I did not manage to built it during the weekend - firstly I had some problems with the power supply board (I switched 200V and 40 diodes - you might guess what happened) and this took me a few hours to figure it out, but I did a PhD from the PS board :)


Now I have to build a 7805/7905 regulator for the tube filaments, but I ran out of 7905s. Tomorrow...

I hope to get this DAC working ASAP.

P.S. I decided to go with the battery power supply at least for the digital PCB. I will also try solid state (JFET) output stage, of course battery powered.
