Oct 19, 2006 · 电子管：信号放大兼直耦推动6AN4 (实际制作时，可以选用国产小九脚的6C3等，参数与小七脚的6AN4接近)；推动级选用300B；变压器推动ГМ-70 (GM70)。 这里ГМ-70 (GM70推动变压器的阻抗比为3k:1k，基本上与300B推805的推动变压器相仿，可以选用成品型号ZS-3011或者定做。 胆坛吸收新鲜血液，招版主，欢迎您的加入！ 并将清理不合格版主. 是国产的FD71吗？ 胆坛吸收新鲜血液，招版主，欢迎您的加入！ 并将清理不合格版主. 喜欢学习了。 …

Feb 20, 2021 · L（低频扼流圈）+ R B即是6AN4的负载又是2A3 的栅漏，10欧可能是限流电阻，用1W小些。 A点滑动改变2A3的栅负压。 （A；B要协调调整，A点作用大）。 (10欧串连有两个调节点的可变电阻器） 2A3 Va（max）=300V 屏耗（max）=15瓦 甲类标准应用 Va=250V Ia=60mA。 图中一， B+=500V Va显然超标，Ia=65mA 屏耗大大的超标，比红屏还危险。 这就要求抬高阴极电压。 图中二， 电压500V用450V电解滤波供2A3 就这个局部电路而言耐压差的 …

Name: 6AN4 Use: Miniature type used as mixer or rf amplifier in cathode-drive circuits of uhf television tuners covering the frequency range of 470 to 890 MHz. Notes: Requires a miniature 7-contact socket.

Dec 24, 2006 · Looking for a good tube, cheap, high transconductance, for a top grounded grid tube in a cascode preamp with a high heater to cathode voltage. Also thinking about the 6GK5 and the 6ER5, & 6DL4. Just trying to find people with experience. Thanks, Ray. I just used a 6GK5 as a linestage buffer... worked great. 6an4 looks even better on paper.

Dec 29, 2005 · I got my 6AN4 from Auntique Electronic Supply. They sell them for $5 a tube, so not very expensive at all. I do agree that there is not as drastic a variation in sound to this tube as there are in other types. But that being said, I did find the Sylvanias a bit bright and forward. The Tungsols and Westinghouse to be more even balanced tonally.
