RE: Cathode bypass cap removed and I like it

Tre,

I found this schematic to help me understand fixed bias. What do you think of using a simple battery to set the negative bias voltage? I currently use a battery on my driver tubes, so I have no adversity to batteries. Unless you advise otherwise.

I am intrigued by the fixed bias method and want to hear what it sounds like. I just need to make sure I understand where the negative voltage should come from and how much negative voltage I should be using for the 2A3 tubes.
