Although I found some article about OTL amps. in MJ, there in no 'Wiggins Circlotron Circuit' or 'The egual to bridge output circuit'.
Almost Japnese OTL apm builder choice cathode follower type after their inqury into others : Hutterman (correct?) , Thechnics 20A type.

Mr Ryozaburo Miyazaki had written some useful article about OTL amps. form 1992 to 1993.
Though I find no his new article in latey years, I think he is able to solved your question.

I advice you that you had better contact with Mr Miyazaki.  MJ will tell you his adress.
