I use a scope, plate current and plate voltage meters.
Final efficiency is typically 75% - so, 1500v @ 200mA = 300w DC input is
close to 225w carrier output.
If you don't use a tuner, and know that your antenna is resonant at the
frequency you want to operate, then you don't need a bridge.
For PEP? Use a scope. Allow your natural asymetrical voice peaks to
rise where they need to, to faithfully reproduce your voice, without
distortion or cross-over modulation at the low frequencies, and let 'er rip.
