Tube 6AG7 or Röhre 6AG7 ID3125, Vacuum Pentode, Octal (Int.Octal, IO) K8A, USA 1935 and Power/Output shown. Radio tubes are valves.

The 6AG7 is an American metal valve designed for single ended audio output stages. Probably for receiver use. The thin metal tube envelope is 25 mm in diameter and, excluding the IO base pins, is 66 mm tall. References: Data-sheet, 1040 & 1043. Type 6AG7 was first introduced in 1939. See also 1939 adverts.

2016年1月5日 · 国产叫6p9p，苏产叫6П9，欧美叫6AG7。 这个管子当初设计出来主要是用作给CRT作做为视频输出管用；6P9P做胆机单端功放取10K阻抗输出牛，但此管做功放用出力较小（2.4W），普遍反映的是中高频较好，低频较欠缺（主要原因是输出阻抗高，输出牛不易做好），设计中可通过电路进行补偿，但此管如以三极方式用于单端大功率管的推动极，则表现出来的效果还是很不错的。 LZ的问题是电路设计或电路布局有问题，这只管子我用来接成三极管 …

2007年10月8日 · There is one potential fly in the ointment: the 6AG7 is really a small signal type. This VT is intended to be used as a wide-band or RF amp that has a large g (m) for good gain with small Rp's. The 6AG7's r (p)= 130K is an order of …

It's not an easy question to answer, but on this page I will walk you through how I came to choose the 6AG7 tube for this amplifier. By following along with me on this example you should get a general idea of how to choose a tube for a particular application.

2004年3月14日 · I have four NOS 6ag7 pentodes in my spares box. Does anyone know if these are suitable for audio use ?

The 6AG7 is a power pentode designed for class A service. It is a metal tube with a maximum plate dissipation of 9W. Is is identical electrically to the miniature 6CL6 tube which was released in May of 1953, but it has a slightly higher plate dissipation than the 6CL6.

2024年10月31日 · 再是美国产各种品牌GE、RCA等的 6AG7，sc航空级的多种，解析力很高，但音色过于刚猛，用时最好搭配英产油浸耦合电容，声音会软许多。 再是小日本的东芝网屏6AG7,声音比较清淡，我的女友却最喜欢它的声底，说有禅味。

The 6AG7 Pierce oscillator drives the 6L6GC, both as a straight amplifier on 80m (sort of), or as a frequency doubler on 40m (kind of). RFC1 resonates the final input at around 5 Mc., close enough to either band to provide sufficient drive.
