Hello friends
I'm having some difficulties trying to understand the theory behind tube biasing, specifically in the following example from the NEETS tutorial:
http://www.tpub.com/content/neets/14178/css/14178_38.htm
My problem is that in the above link they say that "the grid is more negative (-6 volts) than the cathode"
Well how is this possible if in the diagram it refers to - http://www.tpub.com/content/neets/14178/css/14178_37.htm
The cathode is connected to the (-300 volts) power supply. Obviously (-300) is more negative than (-6), so what am I missing?
