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. Jim Bromley, K7JEB Glendale, AZ
