Thanks for this. Direct driving ESL's with tubes is so elegant. So Ive attached the two other pages of this article addressing the theory and build of the DD-amp in case anyone is inspired to have a go.

The 2nd schematics is missing a dot/ground connection. Besides that it is identical indeed, even with the same tubes, as QE06/50 is the Philips 807 equivalent!
Best regards!
