    Post DAC(reconstruction) filter for NOS DAC

    I am here with this DAC design with PCM1704 and the standard circuit provided by BB. As you can see in their datasheet.(Page 9) http://www.ti.com/lit/ds/symlink/pcm1704.pdf But I do not think they did justice with the DAC chip by throwing a simple post DAC filter in the Typical application...

    N JFET Alternative for 2SK369BL/2SK363BL

    I am searching for possible equivalents to use with this circuit. http://www.teddypardo.com/Resources/SuperTeddyReg.html The purpose is to power a DAC with estimated current need of 1.5A at the maximum. They are low noise Nchannel JFETS. Being low noise is critical for the application I believe...

    help with a relay in 640p phonostage

    Hi, I was recapping my cambridge audio Azur 640p (hypnotoad mode)with bipolar capacitors as the initial change. Everything went fine. Then I changed the 100uf capacitors near the regulator ICs as the second step.Everything worked fine for few minutes then no sound from any channels. I looked...

    LOW -PASS filter for cleaner AC power supply

    Hi all, I came across the advertisement about Pangea P-100 powersupply for cambridge audio 640P phonostage. The manufacturer claims that it make the DACs/phonostages sounds better by incorporating a LOW-PASS filter at 12VAC output from this PSU.It also has DC supply but it is the AC out that...
