5692和6SN7GT完全通用,放心替换,下面是RCA官方文档上的摘录:
“The electrical characteristics of the 5692 are similar to those of the 6SN7GT. The 5692 is recommended as a replacement for the 6SN7GT ony where the operating conditions are within the ratings of the 5692 and only where long life, rigid construction, extreme uniformity, and exceptional stability are needed. If the 5692 is operated at the higher miximum ratings of the 6SN7GT, the full advantages of the 5692 will not be obtained.”
RCA官方文档上给的参数是5692工作在稍微低一些的工作电压下量出来的,所以才能获得RCA标称的1万小时超常工作时间,故跟6SN7参数有点不一样。但如果5692也工作在6SN7GT的工作点,5692的性能参数和6SN7GT应该完全一样,但是寿命不再是RCA标称的1万小时了,而是变回6SN7GT的5千小时。所以5692和5691系列的1万小时超长工作时间实际上是RCA的一个marketing噱头,哈哈,如果6SN7也工作在5692的低工作电压下,也能达到1万小时的长寿命
