PP Output Transformers in Jean Hirags Book

In Jean Hiragas Book "LED AUDIO Initiation aux amplis a tubes".
Page 98. Output transformers for push pull amps.
Freq. range. I think that freq. range for Tango, Lux and Tamura is measured at 1 W output, and for Millerioux at full output !
Does anybody know the core size for some of the 28 output transformers ?
