Very generous of you to provide a diagram.   Are you using some kind
of software to make these designs and drawings, like a SPICE
variant?    I think I'd better get something like it.

Curious about two things:

 1) is this common base amplifier an inverting amp?
 2) is there an analog to this voltage amplifier common base
configuration using tubes instead?
