The Digital to Analog Converter


Here some photos of the first customer ordered DAC to be shipped soon.

Besides the black color for the transformer covers and capacitors this unit has an upgrade to the high voltage power supply compared to the prototype.

The PSU uses an ELROG ER274A rectifier in a hybrid bridge together with 2 TV dampers.

For some thoriated tungsten glow from both the main unit and the HV PSU.

The digital power supply is again housed separately.

A peek into the digital power supply shows why, separate choke filtered supplies for the receiver and DAC boards.

The DAC unit:

The DAC will be shipped with ELROG ER801A output tubes. Old production 801A or 10Y can be used as well.

And also an inside view showing the DAC and receiver boards.

Some more infos about this DAC here.

Drop me an email if you are interested in such a DAC for yourself

Best regards
