2021年6月1日 · 日美型号6SL7就是苏联型号的6H9C,二战时期美国与苏联都是同盟国,信息共享,美国援助苏联电子管制造技术与设备,战后由于意识形态不同,分道扬镳苏联把电子管命名国产化6SL7变成了6H9C同理6V6国内销售就是6П6С出口仍用6V6。 同志加兄弟的中国也是沿用苏联的型号,其实是二战美国的生产线。 61年(翻脸了)中国双标6H9C与6N9P ,1962年后国产化只标6N9P 。 总之6SL7=6H9C=6N9P 。 6H9C的参数和6SL7接近,互换使用问题不大。 6H9C的 …

2024年1月17日 · 4.1k对200欧的负反馈比例,可能偏深了一些,想要增益大,只好将4.1k电阻加大到10k左右试试。另外6h9c的放大倍数较小,在屏极电阻100k情况下在线放大倍数可能只有40左右。虽然加大屏极电阻可以增加放大倍数,但在后级栅极电阻的影响下增加有限。
