另外12a_7係咪都可以通用架？例如u7，x7？
唔通用 t7 u7 x7 腳位一樣 但個gain唔同
唔通用
gain 唔同, 電壓、電流規格都唔同，亂用會燒
說明書會講可以用咩膽

el84其實都要match 6189w=u7
6189w=u7

EL84: The power tubes are self-biasing and do not need to be
matched for gain.
12AT7: The 12AT7s should be a matched pair.
12AU7: These are used in the preamp section (the smaller circuit
board) and in the power amp section. In both cases, the 12AU7s
should be matched pairs and each individual tube should have
both of its triode sections matched as well.
Note on using 7062 tubes:
The 7062 is often used as a replacement for the 12AT7. This is
usually not a problem, but they do require slightly more heater
current than a standard 12AT7, which in turn requires slightly less
current than a standard 12AU7. If you want to use 7062 tubes in
the power amp section, you’ll need to replace both the 12AT7s
and the 12AU7s with 7062s in order to ensure that all tubes receive
adequate heater current. You can use 7062s in the preamp
section without changing any of the other tubes.

巴打一玩就嚟10支膽
pair and match夾聲都有排玩
pair and match夾聲都有排玩
一步到位
收到
唔該巴打，咁等我溫左書先
所以夠我玩到個仔大
等巴打到貨開箱
我都好期待
bookmark晒
唔該巴打
入左呢個坑好多功課要做

Bassoon 吃香呀
太貴少人吹學得ok可以考band 1 orchestra勁果啲學校
入門好似都7，8萬一支

幾歲先聽到full size open back
呢度係咪已經個個都玩膽amp了？
