I would think that the stock meter movement would likely be the usual 1 
mA full-scale in either a solid-state or tube unit, so the "talking 
meter" adapter should likely work.  Calibration would be different, but 
I'd think it could be worked out either way.   For dipping or peaking, 
a meter adapter with a tone output option would be handy.

A grounded-grid amp might be the best choice, as you can concentrate on 
tuning it just for maximum output.  A grid-driven amp usually requires 
back and forth between several settings and would be harder in a 
vision-limited situation.
