Look for a pi network on the inputs of half the final
tubes labeled something like "carrier phasing" and
another on the output of the other half of the tubes
labeled "peak phasing". Or something similar. The
only Doherty rig I have ever seen was a homebrew
150 kW monster on 800 kHz in Cd. Juarez. BTW, that
rig was built by one of the founding fathers of
Continental Electronics, James Weldon.
