In Reply to: For Kurt or ? input tube bias? posted by SteveBrown on March 27, 2001 at 11:30:17:
Let me clarify, I hope. I can put 3v on the input of a tube (6N1P) biased at -2v (about 10.5ma,Vp=200v, Ebb=400v), and I get more than enough swing from that stage to drive the next stage (my 300B) into clipping. If I monitor the output of the first stage and the second, the second clips before the first.The question is, what is the concern about the low grid bias voltage that I've read. I don't understand it. And why doesn't an input of 3v (rms) cause a tube biased at -2 volts to clip, since that represents more than 8v p-p? What am I missing here?
Also, as I look at other drivers, what does it mean when the top clips before the bottom? Or vice versa?
Thanks
