Any one? I just want to make sure....
PCB renovations
Hi Peter,
Do you know of an easy way to cleanly cut apart the 4780 PCBs at the score lines -- after it has been assembled? I've decided to rethink my assembly plans and mount the boards separately, rather than all in-one as I originally planned. Except now it's populated and a little more fragile to muck with.
Any advice?
Thanks,
Todd J.

wood and plexyglass. your right it sounds better without the case. i wana try your idea.
That enclosure was posted here: http://www.diyaudio.com/forums/showthread.php?postid=736473#post736473 The acrylic top is mostly decorative and you don't really need it. Don't tighten the screws either.
Re: DAC maximum sample rate
The DAC uses old technology and it will not work with 96kHz.
hayena said:Hi Peter,
you already mentioned the DAC works only for red book CD standard. Would it be posible to mod to allow other sampling rate like 48kHz, or 96kHz? Or is it totally different device? Sorry, just not experienced at digital audio at all...

Hey Karma,
What circuit are you using for the tube buffer? Which tube? Do you have a schematic? Are you using another transformer for the tube buffer or powering it from the dac transformer? I've decided I'm going to get one of Peter's DAC's and was thinking I may like to add a tube buffer also.
Thanks,
Mark

sdedalus said:Peter, Thanks for the quick delivery on the dac kit. Got it today, tossed it together this evening, and plugged it in about an hour ago. Sounds great. Now I just have to wait for the buffer kits.
The buffer kits are almost ready. I got the boards already, all semis, and I'm only waiting for Dale resistors now.
Also, the Integrated Amp chassis should be available in two weeks or so.
Yesterday, I implemented the Patek circuit in that chassis and it came out really nice. Also, it will be possible to use that chassis for a preamp, using either AD815 (it mounts exactly same way as LM3875) or the buffer boards.
The toggle switch on the bottom disconects potentiometer from a signal ground allowing to use one set of RCAs as direct amp input (Integrated becomes power amp then)
