Tube E 180F or Röhre E180F ID18574, Vacuum Pentode, Noval, 9 pin miniature (USA pico-9) B9A and Universal shown. Radio tubes are valves.

2016年4月16日 · 也就是说，e180f的负偏压0.8v，cd机的信号必须先经过音量电位器衰减才能输入过来，不然会出现正偏了，实测单边峰值0.5v以下可以满功率输出了，所以不会接近0偏压，4欧端电压增益16倍左右，8欧端增益23倍左右。

Mullard describe the E180F as a high-slope RF pentode primarily intended for use in wideband amplifiers in telephone carrier systems, radar equipment and measuring equipment. It can be seen that in this miniature envelope is an even smaller valve, this very small size helps to reduce inter electrode capacitances and thereby raises the maximum ...

2011年8月10日 · Last night I found a nice pair of E180F tubes in my stock, would these be a straight swap 😕 seems the only pin out difference is that the screen is connected to Grid 3, all other specs seem close. Any thoughts would be great, as I would like to build another as a preamp and have heard the E180F is a good choice 😕

2013年9月27日 · 其实 e180f，按照欧洲标准的型号命名办法应该叫 ef180，只不过查不到 ef180这个型号。 欧洲管，一般来说都是前面是代表功能 的字母，比如 el、kt等是功放管，ef是小电压放大五级管，ecc是双三极管等；字母后面是数字代号。

2008年5月4日 · e180f管是一只宽带高频放大五级管，常被欧美国家用于高端仪表仪器和精密设备中，用于早间的飞机、计算机、雷达通讯机站和军方高级设备，其特点是工作稳定，寿命长，高频特性好，大电流工作线性好。

2017年11月24日 · First, you need a greater bias than 2V you get with the E180F. And, as euro21 says, "The E180F driver tone is a little thin" for an output tube such as 300B.

The second circuit shows an E180F pentode configured as a mixer with a test IF output of 13Mhz. C1 and L1 are as above. The small signal conversion gain is x10 with the signal generator connected directly to the AC Input as shown.
