William's GG 前級製作實錄

首次跟高手製作第一部DIY前級. 請多多指教.

燈絲半完成圖, 明天繼續

放心啦，William 師兄個機箱可能很高！無事卦！ :

多謝提點.. 等我明天度一度先.

已更改五腳高度

完成第一Part

完成第二Part

今次好靚仔呢！ :wink: 可以睇住自己部 GG 前級一日一日成長，內心既興憤係難以形容！ :mrgreen:

係呀. 真係多謝各高人指點. 希望今晚可以完成放大部份

放大部份完成圖

電源部份

對不記, 想問問 黑色那粒 RS 1005 怎樣安裝?
我見在零件上, 印上  + /  -  , 但底板上沒有任何記號作識別!!!
你們是如何作識別的呢???

請 William 及 各位大哥幫幫忙!!!
THKS!    ops:  ops:  ops:

我猜想RS1005(+)應該對應相鄰的電容(+).
只要跟底板線路找出電容(+)與RS1005接駁位應該就是(+)

明白了!!
thks!!!!

跟Ah Kit所講, 電阻跟底板應留些空間以避免電阻有問題時損壞底板. 電容應貼近底板避免移動時弄斷電容腳. 我已跟指示改好. 今晚貼圖給大家看.

貼圖已更新. 大家可用作參考

Hi William,

Seems the diode in a reverse direction, please check with Kit or Simond.

Take care!

90% 完成度

William

Are you sure you are using the correct cables (Brown & Yellow) for the AC input (12.6V)?  It seems that we should use yellow and black.

Samma

Yes, you are correct, should be yellow and black....

接線已更新,  只差接駁地線就可開聲

完成!!!!!!! 等待開聲!!!!!

真高興, 總算開到聲!!!!!

但在測試時發覺不開GG volume 開大後級左邊有D See See 聲. 請問有什麼方法解決?

Hi William,

Congratulation! See...se.. sound may be come from tube or solder point of resistor. You can try interchange the position of tubes and triple check all the solder point. Good luck! See you tomorrow.

升級!!!

1. 面板
2. 開關
3. auricap 1uF

Yeah!

Excellent!  

BTW, would you please tell me how to do like that ?
i.e. how to make a LED light ?
and; how to make a switch on the front panel ?

Thank you very much!!

海記: I bought the following items from DIYZone (Kit can help to order too!)

1. Upgrade panel for Entry 60 Case (come with 2 big holes and the middle LED hole and 2 knobs)

2. Power switch

LED connection
==========

I connect the LED with a 1k resistor to the 12.6V output (share the power with the 燈絲)

+ 12.6V -

Switch is easy, just connect the power plug L & N to the power switch kit and output to the transformer

Hi, William,


Thank you very much!!!   =D>

Hi William:


If you connect LED (blue), will it affect sound quality ?

Thanks
ahwah

As LED just take very little current, it should not affect the sound quality

Thanks William !
