Working on the above design, part way through obviously. This is my first design from scratch, and not really helping myself with some complexity but in any case I'm giving it a shot. A few things need revision (300b cathode resistors at center taps not filaments, many values left to calculate), I'm obviously not done but had questions before spending too much time in the wrong direction.
The biggest area of uncertainty for me is the driver. Does the requisite cathode voltage develop from circuit conditions or do I need to apply a voltage to the top of the CCS? Does this input/driver DC arrangement have a hope of being stable?
Any other reasons this is a non-starter?
Thanks in advance.
Dave
