Default DAC's and parts for sale

I sell my DIY Dac because I'm satisfied with the one which is within my player (equipped with PCM1702).

The DAC is composed of 3 boards, one DCA board, on dual mono PSU, and an additional 5V PSU.

The input receiver is the CS8412, the digital filter is the DF1700 and the DAC's are the PCM 63 in K grade (highest selection grade).
I/V stage is discrete, output stage is capacitor less, and comes with a OPA2406 per channel.
The whole thing is housed in an aluminium cabinet, black.
The PSU is wired to 230V, but it can be changed to 115V, since the trannies have dual windings. The IEC connector has an integrated filter.

The DAC board and the dual mono PSU come from a well regarded (at least in France) player, the Cairn Ecrin, released in 1997 or so.

The sound is good, but can be improved (Cairn obviously used the BB application strongly), but the nice design and layout allows mods, to set this device into much higher levels.
I don'y have the time right now, also I'm moving abroad and I try to sell a maximum of parts.


I have also a DAC Lite (asian product) which uses 8 TDA1543 in parallel, a CS8414 input receiver, no filter (neither digital or ouput). It has tripe PSU, with one large (80VA) toroidal transformer and seperate windings for two digital and one analogue section. Ouput OpAmps are OPA134 (one per channel), coupling caps are Black Gate NP with Audyn Cap SN in parallel.

No housing for this one: build it in your own, or build it i your player.

Also for sale:
- OpAmps (OPA2604, OPA2134, AD825 with adapters (single and dual), LT1128 etc.
- A complete rail with 36pc. TFA9843J (2 channel ampplifier 2x20 watts) brand new & unused
- A complete rail with 29pc. TDA3681 ATH (multiple voltage regulator)
- A set of rails with in total 252 TFA9843J chips (see above), still sealed.

Please inquire for pics or more description, please make offer for the mentionned parts.

Will post some pics soon, and an exhaustive list too.
Ship worldwide (prices according to weight and destination).

Everything has to go before november.

Cheers,
- dan

No balanced version, if you need a balanced output I suggest some Sowter or Lundhal transformers with excellent results.

I think to get 300 € for this DAC.

Pictures will follow.

Cheers,

Default Pics posted

A while ago I posted some parts for sale, but my camera wasn't working. It's done now, here are they.

This one is the PCM63 based DAC, from the front, open cover.
From left front, clockwise:
- dual mono power supply, fully discreet (no LM's or so). Tranformers are wirde to 230 volts, can be modified to 115V.
- Input ICE socket with filter (Schaffner)
- Switching power supply (high quality type from a audio device) delivering 5 volts for digital. Can handle 100 - 240 volts (without any change).
- Large converter board

This pic shows the power filter (Schaffner), and the HQ switching power supply. It's coming from an Altec Lansing device and delivers clean 5 volts for some digital section on the DAC board.

This is the DAC section:
- Left the 2 PCM63 in selected "K" version; the DF1700 filter and the CS8412 receiver. Sorry for the quality, with flash it's too bright, without too dark!
