Hi, Raymond!
If you find capacitance values you need on this page and you think their prices are reasonable enough, サンリング PPSD please let me know by a usual internet e-mail. I will buy and send them to you. Bunpei |

The CQ09R2E 0.01uF (due to physical size) are the one I need. Quantity vs. prices must be checked as I need them in hundreds or thousands.. Do you have contact info for SunRing directly ? |

If you purchase their product as an audio device manufacturing company, you can contact to TOSHIN KOGYO Co., LTD. in Nagano, Japan directly through their web page.
Contact-TOSHIN KOGYO (You must clearly specify the "Sun-Ring" brand name and the capacitance in your inquiry.) |

Some of you may not believe this claim.
However, I'd like to recommend SDTrans users apply such tiny bead cores on a DC +5V power supply line of SDTrans. The product is originally a "surge absorber" that removes "spikes" in a line. A Japanese friend of mine told me that it was also very effective for improving a total SQ of SDTrans. First, I thought it must be exaggerated somehow. After trying it with my SDTrans actually, I realized its effectiveness. In the yellow circles marked on the pictures, you find the bead cores. You can read an explanation of the product here; Surge Absorbers : Amorophous Products : Hitachi Metals America
An externally hosted image should be here but it no longer works. Please upload images instead of linking to them to prevent this.
The key of the bead core is "nanocrystalline material". Domestic list price of the bead core "Black Pearl" is 600 JPY (= 6 USD) /each. I think it is worth trying really. If you are interested in the product, please contact to Mr. Teramoto of the following e-mail address; iphone0123 < at > goo < dot > jp |

Are there any reason why it is the PPSD series that have been used for audio in Japan and not the PPSC or PPSO series? PPSC,PPSD,PPSO Series High-end type film capacitor for audio equipment ●Electrode consists of Copper foils and dielectristics of polyphenylene sulfid films. 電極は銅箔、誘電体はポリフェニレンサルファイドフィルムで構成されています。 ●Excelent temperatur characteristics with flat capacitance change. 静電容量の温度特性が極めて優れています。 ●性能/Performance ・Category temperature range: -25℃~+85℃ ・Rated voltage : 250VDC ・Dissipation factor : 0.005max PPSC Series ■Capacitance / tolerance ■用途例/The example of Use Coupling circuit with electrolytic capacitor 電解コンデンサ一緒にとカップリング回路に使用 PPSD Series ■Capacitance / tolerance ■用途例/The example of Use Equalizer circuit and Feedback circuit. イコライザー回路、フィードバック回路に使用 PPSO Series ■Capacitance / tolerance ■用途例/The example of Use Amplifier circuit of very low noise. 極低雑音増幅回路に使用 |

Manufacturing of the PPS Cu-foil type capacitors was recently passed over from Sun-Ring Company, a very small company, to Toshin. When Sun-Ring manufactured the caps, they used to sell only the PPSD type in a market. That's the simple reason why audiophiles in Japan only used the PPSD type.
I'm not sure whether other types PPSC and PPSO are suitable for audio use or not. Why don't you request a small quantity of samples and evaluate them by yourself? |

Product release version of Chiaki's SDTrans-Sync-9018D DAC + I/V system is in the final checking stage at Tachyon shop in Tokyo. Mr. Yamazaki of Tachyon is concentrating on the task.
Attached are pictures of three board. Next week, Mr. Yamazaki will send his messages to those who has made preliminary reservations. If you are newly interested in these boards, please send your e-mail to Mr. Yamazaki jack < at > mtc < dot > biglobe < dot > ne < dot > jp to ask whether the kit is available or not and prices. Though he said all the boards in the first batch are already fully assigned to preliminary reservations, there may be some cancels. The 1st Picture: 9018D DAC board (ES9018 Dualo Mono DAC with 40s MHz NDK oscillators), Top View The 2nd Picture: 9018D DAC board, Bottom View The 3rd Picture: I/V (AD797 op-amps) board, Top View The 4th Picture: I/V board, Bottom View (Joints to the DAC board are shown) The 5th Picture: The I/V board is stacked on the DAC board The 6th Picture: Sync-option sub board for SDTrans (The white part) |

Thx for the photos! Looks real good :-)
I canエt wait to get my hands on the dual-ESS9018-mono-mode-DAC and the IV-converter. Lots of power supplies will be needed, so I am working on that now. Of course I also bought some solar panels ![]() ![]() /S Quote:
