I really don't understand how this circuit regenerates. Maybe if
someone could explain that I'd be in a better position for
troubleshooting.

They apparently vary the suppressor grid resistance to ground; it uses
the internal capacitance between the plate and control grid to provide
the regenerative feedback. Moving the suppressor further from ground
deminishes the isolation the suppressor normally provides between the
plate and G1.
