我的QUADII胆機開工

所有零件除了電源濾波用的choke外都準備好,開始動工

多謝KK SIR, WILLIAM, MODI 的意見

請各位大佬在我裝機的過程中多給意見, 因小弟是DIY新手一名  ops:

DAY 1 - 電源, 燈絲, 火牛, 電制己裝好

想問電源線如果是多股柒皮線, 是否要用刀先批去外柒才能上碭?

試過都好難上...

[quote:32f03c5d87="modi"]點解你所有膽的燈絲電壓都是並在一起呢？
是否有一些問題呢？[/quote]

:shock:

吓! 問題係咩? 請指出讓我可修改, 唔該!!

今日完成大部份搭棚, 想問接地的電阻點樣最好點樣搭, 直接銲接在粗銀線上, 再接機箱上嗎?

再貼

[quote:ece370260c="la1209"][quote:ece370260c="modi"][quote:ece370260c="la1209"]多股柒皮線比較麻煩！
方法是用焊槍在線芯的橫切面上一邊加熱一邊落焊，你會看到線上的柒會起泡並慢慢退掉。
但焊槍火數要夠，最好將線材固定才做比較容易[/quote]



所講的是可以的，但不是每一種線都得，而且烙鐵要去到四百幾度先可以做到！[/quote]

這當然啦！如果是很粗的柒皮線就不可以啦！
我講的是Cardas Litz wire，去到12AWG到可做到。
8) 小弟是用可調温度的恆温焊台[/quote]

:roll: 明白明白...

多謝兩位大佬的意見!

但燈絲電壓都是並在一起是否有問題?

[quote:8ed7a0b02c="DUALXEON"]開機前不要忘記用綿被包好(防爆裝備).

[quote:8ed7a0b02c="modi"]另外好狗兄你要上一上搭棚初班呢？ :[/quote][/quote]

ops: 如果有discount給我都會參加的, 哈哈...

不過可否講吓試機的安全步驟?

另外, 大家可否睇睇個濾波用的choke是否要用到60H咁大. 唔該晒!!

小弟先排經常出差, 今日終於完成, 可以試機...

唔知那裡買胆好 :roll:

大家可以提議一下嗎?

另想問下輸入牛輸出端400-earth-400, 在未裝整流胆時直度400-400端有~745v是否正常(因未有回路)?

請大家解答, 唁該

[quote:9e60b8ecd2="DUALXEON"]好久兄

I am interesting in your tubes. Pls reserve for me. I am going to buy after testing.

But pls advise the price of EF86 Sovtek. Thanks.

胆出現藍屏代表什麼問題? :cry:

請大家幫忙

Finally finished my amp as I am so busy recently.

This is very valuable experience as the whole DIY processes were done by myself starting from data gathering, buying components, assembling, testing...

There is still low level of noise when hearing close to the speckers (with low frequency hum sound).

Now my pre amp, amp and speckers are all DIYed!!

thanks, ozrayyau.

i will try to search the tubes! 8)

BTW, if there is low hum sound (may be from AC filment), can it solved by adding parallel resistors (50n) on filment connecting to earth?

Pls anyone can give your opinion ...

[quote:19e162415a="ozrayyau"]有樣睇,唔好買錯 :wink:[/quote]

I have search on eBay and Chinese web and could not find the E80F tubes.

Pls could you provide the source? :roll:

Or do you have any spare?
