    But from other forum, some say

http://music-electronics-forum.com/t5518/

"The bias level for the EL34 would have been way too low for the 6L6, so the 6L6 burnt itself up. To do such swaps you would need your bias to be adjustable."

Very good.

呢D理論只會發生在電容漏電, 電阻變值時, 正常無問題既機絕對可以直代.

你部咩機? 2支定4支EL34?
我最近b ...

Mine is Mini II SE /push -pull from Audio Space
The tube labelled as EL34 only and I brought a replacement set of Svetlana also EL34, so it is pretty sure EL34.

Well that is very nice of you to offer me a trial. will PM you separately.

    早兩天,到百宝利想話聽下部2A3,
點知話已賣晒, 連demo unit 都無!
最後聽過下部300B/2A3 兩用機, (用300B)

感覺唔到有乜特別, 我唔係話唔好聽! (其實大多數demo 既机都好好聽)
我係話因為冇得比較,晤知2A3 同300B 有乜聽感分別!

反而發覺自己好喜歡那些大尺寸嗱叭的聲音, 有種"老"的味道!

但礙於居住環境,相信用大嗱叭都係機會微!

另外,超高音配全頻unit 係點樣配 大細聲的? 要配單元効率嗎?
分頻就好似係用電容或built-in 分頻 ,係唔係呢?

覺得唔值…

Ching think what is "唔值"? the 2A3 amp?

But have look around, price for different brand sound about the same.
also though about join one of those DIY class for making my own unit form a kit, but the total price will be just slightly less.

Do u have any recommendation??

師兄經過中環的話，可上reference audio聽下部sunaudio sv-2A3, 此型號已經俾stereophile 評為class A component, 機身零件和聲音也有一定質數的。

    先謝過ching介紹, 可否告知這部sunaudio sv-2A3 約價多少??
另在網上search到很多人提及clone Sunaudio 2A3 等等, 那reference audio 這部是clone 板本嗎?

此機由日本入口到香港代理處應是套件來的，也要萬多些港元(全機四隻tamura火牛和堅固機箱也值依個價),如由香港代理砌埋要另加二千港元，上代理處聽下和同老闆吹下水都無妨的。如要上多級便要考慮audio note 的單端2a3產品了。
