John/WA5BXO runs 2400v on his (4) 813 (push-pull parallel) modulator, 
and ~1200 on a pair of 250TH's.

He used to have a rig that ran a pair of 304TL's, that ran 1300 or 1400v 
on the final, and the same modulator (same voltage).

The voltage on the modulator is what's needed to properly modulate the 
amount of carrier produced, without flat-topping or causing distortion.

Driving your AM Rig without a scope, 
is like driving your car at night, without headlights. (K4KYV)
