Peter, if you get a chance, have a play with the AD811 as an output. It's a really good line driver, can drive difficult loads, and sounds really nice.

Peter, that layout looks great. One thing though Please consider placing an extra pad on the resistor footprints to allow proper mounting of standard resistors with 300 mil lead spacing. That way it will be possible to build both a high-grade version with caddocks/vishays or a more standard version with standard metal film resistors. Shouldn't be much of a problem and it makes the board a lot more versatile IMHO


/U.

Actually that board was never really designed with Caddocks or Vishays in mind (although they fit there perfectly). With the kits Brian and me are selling, we are using those 0.5W resistors from Phoenix. They have 0.134" length and fit well in 200mil footprint: http://dkc3.digikey.com/PDF/T051/1011.pdf

If there is more interest in 300mil footprints, I might try to implement it, but this will somewhat affect the planes, which are already looking like Swiss cheese

I received my PD SE boards today.. They are byooo-teee-full. I'll wire them up when I have some time -- I have about 20 other DIY projects I have to finish first I'll probably have to save some of my pure-silver wire to go with my gold plated boards.

Dang. Some of my DIY stuff is starting to look like it belongs around a Rappers neck!

Peter,

I would be interested in either a DAC kit with the board and critical parts or a full premium kit, depending on my finances.

Would the power and input transformers come with the partial kit? Sometimes it's hard to find parts like this that fit exactly in the circuit board's holes. Then you have to buy and pay extra to ship the same parts anyway.

Thanks,
KT

KT,

I should be able to deliver any parts needed for the DAC. It does not feature input transformer though, I prefered the sound with an active driver.

Mike,

I only had two sockets available at a time. Whenever I'll get to Sayal I'll get more and send them later.

I will have the DAC boards tomorrow. They are made the same way as LM3875 SE ones

Thanks Peter. I may have to pick up a DAC kit as well. I'll have to see if my Superdac 2496 is revivable or not But I may pick up some of the basic parts anyhow -- I've always wanted to make my own DAC.

Thanks again for the great service and sweet lookin' boards.

Mike
