Yeah,
Rick just told you all the reason why I cancelled my "balanced Szekeres" project.
Anyways, in PassDiy's Son-Of-Zen type (or MOSFET differential amp), can made to accept UNBALANCED inputs. You can simple connect one of the input to ground. Note this will effectively kill any advantage of building BALANCED version. ... Yeah crap. ...
Instead what you want to do is to build a UNBALANCED-to-BALANCED converter. This is fairly easy with a single opamp.
Also, there is another thing you can try. Observe the original Szekeres amplifier schematics. You may be able to take signals from DRAIN and SOURCE of the MOSFET to get the BALANCED output. But I cannot confirm this.

P.S. About fire hazard thing, you can ask Mr. Corleone to "take care" of the problem at his birthday party. According to the movie, Godfather can be very "persuasive" if he wants to be. ...
