Posted 8th October 2009 at 09:11 AM by androidDIY

I am looking for a MC catridge.For higher budget, SPU Synergy GM is a good choice.

SPU Synergy GM
The SPU Synergy GM modernizes the classic SPU design with a number of optimizations designed for optimum compatibility and sonic purity. The SPU Synergy features a wood-based housing and has a revised generator system which allows for a maximum output of 500µV, relaxing the requirement for high gain transformer or active preamplification systems. While still making use of a highly polished Nude Elliptical stylus, the stylus tip mass has been reduced significantly, resulting in reduced VTF and higher tracking ability.

Technical data
Output voltage at 1000 Hz, 5cm/sec. 500 µV
Channel balance at 1 kHz <1> 23 dB
Channel separation at 15 kHz > 15 dB
Frequency range at - 3dB 20-30.000 Hz
Frequency response...

Sony HA-T10 MC Step Up transformer

Posted 8th October 2009 at 08:59 AM by androidDIY

Click the image to open in full size.
When I was young,I like to build the MC pre-preamplfier for myself.But the hum/noise reduction is always a very big problem.

After using several excellent input transformers like Jensen,Lundahl and UTC,I should change my concept.
I will prefer using MC step up transformer in my system.Sony HA-T10 is very cheap is easy to find in Japan.I will ask my friends to find some for me and start the way.

Yes,I will try Jensen and Lundahl later.
Another question is - where is my MC catridge?


Description
The Sony HA-T10 is a high quality super-mini step-up transformer, which can be used with moving coil cartridges in the impedance range from 3 to 40 ohms.

The optional RK-125 connecting cord is available to connect the HAT10 to the main amplifier to nullify hum.

Specifications
Matching cartridge impedance: 3 to 40 ohms...

I found an website yesterday.The owner seems to be a professional reporter who wrote lots articles associated with the Japan Adult Video.
It's really interesting,I never thought the Japan Adult Video could be analyzed like that.

Here is the link - http://avno1.com/

相信在十月一定有不少人在期待天海つばさ(天海翼)這位新人吧?畢竟在Ideapocket舖天蓋地的宣傳 之下,大家都想知道這個「アイドル顔負けの超美少女」(臉蛋不輸偶像的超美少女)的新人究竟是不是真貨;而 在寫真照片公布之後,更有人拿她和ideapocket之前培養出的超級彗星初美りおん(初美Rion)相 比,可見這位天海つばさ(天海翼)是讓眾人多麼期待。

Does this sysem support Chinsee?


OK,It works!
I could use this as my blog.....

Cyrus 1 Caps

Posted 7th October 2009 at 04:16 AM by lrseries3

Hi, anyone know how to determine the polarity of old Elna caps? They are orange electrolitics but have no indication of the negative side.

Thanks Stuart

Is a Room correction trial possible?

By burning a corrected CD, you can easily understand DRC indeed works, but with 1 or 2 bits resolution loss. That's due to the equalization of magnitude frequency response.

Using 18 or even more bits is a must.

Beast with a Thousand JFETs

I guess it's time to unveil the Beast with a Thousand JFETs.

Here's the first teaser, a circuit panel to hold 588 JFETs and
associated resistors.
What can I say. Its a pleasure to see a master at work.
