The fail diy diary -2

Prepare two plastic turntable ,copper roller and drill holes
 for mount magnets installation on bottom side.


Top side insert magnets and setup magnetic pole.


Buy a cooking pot and modify it for suitable assembly turntable later.


Modify pot to be a magnet mount rack. 12 pcs alnico magnets will on this rack.


The magnet rack drill a big circle for embed a plastic turntable.

Embed together to find screw hole distance.

Finish assembly.

Try turntable rolling on magnetic floating platform and estimate distance of float.

ToyX project EQ Linearizer study ....Add Output transformer

Attach modify schematic drawing.
Fix impedance for better audio matching.

Modify R channel wire connection and add OTP.


Modify L channel wire connection and add OTP.



First time just modify one channel and after A-B test decide to replace two channel together.
響應較佳 ,音像刻化, 音場,音色線條深刻都有更進一步, 自然.

PL519 Power amplifier for plasma tweeter RF radiation and Heater  40V.



Under testing picture and test plasma radiation.
Modify PL519  plate current about 150mA for A,B test.


德國 VALVO PL519    音場淺且後場有些交代不清,音像較凸出, 音色較厚些且硬一點. 
PL519 plate current over 220mA tuning to 150mA.


德國 SIEMENS PL519   7Khz~15Khz 響應較佳 ,音像刻化較深, 音場深,音色線條深刻化清楚, 且深動自然.
PL519 plate current over 200mA tuning to 150mA.


法國 MAZDA PL519  音場刻化較深, 但音色線條清瘦 ,空洞, 音色偏冷.
PL519 plate current about 150mA.

...離子高音
Acapella另一項特點就是離子高音（ION Tweeter），所謂離子高音是利用真空管昇壓放電產生電離發聲，由於沒有振膜，所以質量為零，高頻發聲完全沒有延遲，是非常理想的高音（或稱超高音）設計。雖然離子高音的設計原理近乎完美，可是怎麼沒有大量應用？道理不難理解：太貴了。Winters說Acapella的離子高音以西門子 PL519真空管震盪，裡面還有石英管做阻尼，大部分玩家都知道真空管有壽命，時間到了之帶該換，但可能很多人不知道，這根石英管也有壽命，使用年限大約十年，時間到了應該更換，以國內銷售Acapella的歷史來看，可能有些發燒友自家的離子高音應該換石英管了，如果有需求不妨與代理商洽詢，尋求正廠零件更新。
...after test some concept come out
1.There design audio system concern harmonic distortion of amplifier.
2.There concern components affect sound color.
So there choice SIEMENS PL519 too.

My final system combination is 5U4g+EH 6C45Π+SIEMENS ECL82+SIEMENS PL519.
