Default ESL-63 question

Hi, quick question on the ESL63 step-up transformers - does anybody know the ratio of these? from the schematic posted at sheldon's world ( it seems that each speaker has two transformers for the two polarities...
thanks in advance
PS: yes I searched andcould not find anything around here.... one post was talking about "more than 1:200" but no more precise than that......

my Infos say 1:260-1:270. Any of said numbers means a ridiculously high value. But the concept of the ESL63 demands higher transformation factors than other designs

quote from the Baxandall article:

" the Quad Esl-63, where two seperate transformers, each of ratio 1:122,5 are used to drive the plates, rather than a single transformer with a centre tapped secondary."
