我有一個5150。。。但感覺太過失真大。。沒有清音。。
但是看過臺灣有人換過3根ge5751上去。。說就能有清音了。。
聼說12AX7也分很多型號。。5751 ECC83等一大堆。。
其實5150的gain我也扭到了5 6左右就再沒法扭了。。我想換tube后能
扭到8 9 10 左右有現在5 6的gain。。然後扭小一點能有清音。。這做得到的嗎?
而且 5150 的中頻很中空的感覺。。很鋒利。。。換ecc83聼說中頻會甜美豐滿一點。。。
所以我想換3根5751 兩根ecc83去試驗一下。。
但是想問一下。。前极12ax7也要配對的嗎?看網上同一品牌型號也n個價錢。。。完全不懂。。。閃大或各對tube認識深的朋友可以講解一下tube嗎??
[問題]關於tube的問題。。

5150嫌清音太dirty要變clean一些, 這一直全世界到處都有人問, 我隨便去搜一篇轉貼過來:
This amp has 6 (that's right - SIX) gain stages and five 12AX7 hi mu preamp tubes.
In distortion mode with the Lead Preamp set to 10, when the amp is cranked
around 6 (if you can stand it that loud), the distortion suddenly kicks into a
very creamy tone. I use a Sholz Power Soak in between the amp & cab to
dial down the volume.
However, the downside is, the configuration of the 12AX7s makes the clean
channel not so clean and the distortion channel pretty noisy & hissy.
To clean up the clean channel and calm down the noise, just swap out one or
two of the 12AX7s with the lower mu 12AT7 (or an even lower mu tube of 12AU7).
I'd recommend 12AX7-12AT7-12AX7-12AT7-12AX7 for a first listen but swap
them around until you get the tone you want. The amp will still keep in gainy-ness
but lose some of the noise
把12AX7換成gain比較小的12AT7, 或更小的12AU7這在很多amp或有tube的效果器
都可以這樣做, 但是有時候會音色就沒那麼好了, 或是觸感, 動態反應等變怪怪的, 要有
心理準備, 人家當時設計這amp時, 我想設計藍圖裡應不會有讓使用者亂換tube也會有另一種
好音色的考量, 應只是就原來tube型號為基礎去設計, 有的話, 那應就要寫在說明書裡讓
使用者有選擇囉!

沒人有興趣聽你在那邊音階爬上爬下啦! 表演一首完整的歌來給我聽啦!
什麼??? 沒有一首能好好完整表演??
你這幾年在學什麼東西呀???
