For reservoir ... I love Mundorf, my VT-25 is using it in first filtering, Philips BC after Choke.
Cathode bypass capacitors I'm using 快晴.

之前買了些俄佬PIO高壓電容未試過，不知效果如何？
#52 [七仔], 25-01-07 11:57
又多幾個位可以玩，呵呵 ^^

Besides the coupling capacitor, the reservoir and cathode bypass capacitors would have significant influence on the amplifier sound character too.

Never ending games.

MCap silver oil 是頭一隻不是天價而又特別好的交連電容，初出差不多馬上買，用了近二十年。後來者可以造得更平宜，體積更小，表現更全面更出色。

之前用過古董油浸維他命Q，九十年代頂班的MIT RTX都用過幾對，MCap 也用過不同的金銀油浸。

膽新不如舊，而電容新比舊好，這麼多年來電容是有長進的。現在比MIT RTX好的電容有的是，上癮的。

用緊GAD-viva 金銀油，好聲但run-in時間比較長

播人聲低音炮趙鵬外婆的澎湖灣鼓聲人聲真係可以好沉好過引.

近年來我部 VT-25 已轉用 Amtrans AMCY Golden Black, 呢粒野當開聲後真係唔簡單!
無論 Sade Hang on to your love 嘅低音彈跳力, Kenny G Going home 蕩氣迴腸嘅色士風演繹, 童安格其實你不懂我的心絲絲入扣嘅人聲都令你不能停下. 就算唔係播 Hi Fi 碟都好好聲.
最近見到 Amtrans 新出咗粒 AMCS Golden SQ, 相信我好快會試.

#43 是美元，郵費另計。

Upgrade the coupling capacitor doesn't help much. There are different ways for the improvement.

I understand the price of the V-Cap is way too expensive. I don't think it really worth.

七師兄， V cap網show出的價錢是港幣嗎?

MIT RTX 聲音中性平均，用它不會走偏，是穩陣選擇。

貪心一點的，希望更幼細，高底更自然延伸，動態好，表情豐滿，更觸動人的音樂表達，可以試試 V Cap:

要是夠位，最好用 CuTF，其次是 ODAM 也完勝好多貴野，包括 M Cap SilverGold Oil。吾人不如這裡各位師傅，不會砌機只會摩機，由原裝的 MIT RTX 和 PPMFX 摩到 V Cap，用過好多不同的 Cap。這是不會改變音色平衡而明顯更優秀之選，用 RTX 試岩數值，不妨直接換相同數值的 V Cap 試試。

Cody師兄，我未買，有冇推薦？

如果師兄已買, 照用啦, 唔好浪費.
如果未買... 應該有更多選擇嘅.

師兄們，請問Mcap Supreme aluminium質素如果，小弟部單端EL34想換粒0.68交連電容，麻煩各位！

RGN2004 , 6SN7, 45 SE.
Really good sound.

I love RTX too, it sound all rounded. If someone don't want to waste time and money to test every capacitors, this one is for you.

Year 2015 I build this 45 SE was using RTX 0.22uF as coupling capacitor, I'm really really love it, and this amp accompany me for years... however after I build VT-25...it over.

Direct coupling is the ideal solution. Unfortunately, it is the task of "almost mission impossible".

Using high quality coupling capacitor would be the compromise.

I shift the message I put into another thread to here

Film 交連电容好多用起上嚟高音細節不清，中音有附帶怪音，低頻線條模糊冇勁力，我用到搶錢Audionote銀油浸都係咁，唯一我用過價錢合理而又高至低線條清晰有勁力係MIT RTX，RELCAP RT

再講返果D又貴又唔係用高級介質交連电容，我試過最少二三十款，果D 痾到碌銀油浸电容真係靠吹噓，自己試過就知

不過又係果句，最完美交連电容係冇电容，即係直接連結，所以千方百計設計個綫路成直結係有意義
