Douglas a couple of questions for you. Someone on the Asylum mentioned your name for questions about E-Linear amps. I was wondering if you could explain the benefits of driving driver tube the with the ultralinear tap of the transformer. (http://www.pmillett.com/elinear.htm)

Also in general, can you or is there any benefit to placing a constant current source or a plate choke on the grid of the output tube instead of a resistor when running a tube in pentode mode ? I've never seen this done, so this may be a really stupid question. Thanks for the help.
