Face lifted "No oversampling dual DAC with tube output buffer."

We have face lifted our nos DAC with new control board pcb, new tube buffer pcb, new front plate pcb, IR remote control and some new pictures. We have also replaced the  aluminum front plates, and the DAC facelift is completed.

Our design are inspired by Lesha's DAC and below you can see some pictures of our design in my brother's version (click on the picture to enlarge it). If you want to build the DAC take a look at this diyaudio.com thread, tube-lover has made a complete kit quite similar to our design.

Note that you have to use a Sony compatible remote control with the nos DAC.

Close-up on the two digital to analog converter TDA1541A hidden behind heat sinks with new pictures. I have changed the capacitors back to 100nF polypropylene as I was lacking treble and my brother was not!		PCB file updated 2008.02.02.
Old S/Pdif interface with new picture.		PCB file updated 2003.12.31.
New S/Pdif interface now with re-clock circuit and improved PLL filter (schematic not made yet). Important! Remember to remove jumper J1 and J2, when not using re-clock.		PCB file updated 2005.04.10.
