Tube 3A5 or Röhre 3A5 ID4281, Double Triode, Miniatur-7-Pin-Base B7G, USA 1940 and Power/Output shown. Radio tubes are valves.

Nov 28, 2021 · 肯定有的，3a5太敏感了，她就像是一个高灵敏度的拾音器，别说震动了，对着吹口气都能出现麦克声，喇叭 ... 曾经想做密封管罩，一直没空试过. 点评

Cytochrome P450 3A5 is a protein that in humans is encoded by the CYP3A5 gene. CYP3A5 encodes a member of the cytochrome P450 superfamily of enzymes. Like most of the cytochrome P450, the CYP3A5 is expressed in the prostate and the liver. [5] .

The test we did was for a gene called Cytochrome P450 3A5 (abbreviated CYP3A5). This gene makes an enzyme that breaks down, or metabolizes, medicines in the body. Breaking down a medicine can either make it work as intended or make it stop working. It’s common to have slight variations in the CYP3A5 gene that affect how the enzyme works.

Cytochrome P450 3A5 enzymes, known as CYP3A5, break down some medicines, including medicines used after a bone marrow or solid organ transplant. Each person differs from another at the DNA level. Genes are segments of. that act as a …

May 11, 2021 · 想知道一级3a5增益是否足够推动。 我现在的4P1S供电电压比你的还高了几伏，到4P1S屏极电 ... 推不足，3A5只有10倍，用现代音源还推不足，更不要说0.775VP-P。

The 3A5 miniature double triode is for dry battery operation. Uses would be in radio receivers and other portable equipment. The thin glass tube envelope is 17 mm in diameter and, excluding the B7G base pins, is 47 mm tall.

Oct 11, 2024 · 1，开机的怪音是3a5电源过于延迟带来的。去掉6p1和那组电压，也换成k2611，输入接到275v上，稳到175v。 2，毫伏表测试的是宽带噪音，人耳对50hz的灵敏程度比100hz差的远，也就是说50hz的3mv，感受跟100hz的3mv完全不同。50hz很多喇叭放不出来，人耳听到的也弱 …

Jun 30, 2024 · 用铅笔轻弹3A5才会有轻微的敲玻璃声音，看来根本不用担心什么麦克风稻克风的，交流声才是关键所在。 下面是前级图及拙作。 最近还在筹划牛入牛出的3A5耳放。 估计尿还得流哈～ 期待老哥搞定交流声！ 你好！ 这得慢慢来了，我估计这个要求不能高了，争2mv保2.5mv不知能不能搞到？ 麦克风效应与增益有关，该二管的增益都低，约10倍和8倍。 看电路图是自偏结构，二个声道要用4组灯丝，不能合用。 已经直流点灯了，按理说不应该很大交流声啊。 交流声 …

细察与一般网上见的有2个明显不同，1是：管肩上没有3a5的蚀字。2是：屏极不是黑色的，是一般的金属色（象6n2屏极那种）。 请教:1.为啥有的麦克风效应严重,有的基本没有? 2.黑屏和白屏有何讲究？ 3.一般3a5有哪几家生产?无字情况下如何区分? 4.各家的电气性能 ...
