Hi Dennis,So you were running two SE amps in parallel, the signal at each output tube grid was in phase WRT the other, the in phase signals at the OPT secondaries were added to produce twice the output power?
From what I can gather, the idea is to have the flux/current relationship operating 180 out of phase with respect to the two output transformers, that way the non linear function simply cancels. I suspect with simple bridged SE, the non linearity is added?.

Shane
