Hi looking at DAC End 2 - the AD1865N-K with single ended vacuum output stage and the measurements in particular. 2.67% THD??? Is this right as the original DAC End measures well under 0.1% in all measurements.

Hi, can someone advise me if these transformers will work design old end dac salus shunt for DAC. I understand I need 9/12 volt 300ma x3.

10 v center tapped
EDCOR Electronics Corporation. PWRC10V2A-1

Any other suggestions of where to get such power transformers i the USA. For the I/V power supply I found a good 250v and 9 volt from Elcor, but cannot seem to find these 9/12v transformers easily besides those for lights. Would it be necessary to use a better quality audio transformer here?

thanks, John

I made a run of power transformers for the Salas shunt regulator and still have three of them. They are six 9 vac @ 200 ma windings and are heavily shielded to cut airborne radiation. A number of folks now have them in use. PM me if you are interested.

Has anyone physically separated the ground trace between the ANA and the DIG on the older Dac Board PCB and reconnected it similar to how the new one is, referencing the connection diagram?
