Default PP-1c as Ultralinear

As suggested by Dave from Planet 10 I'm thinking about using the PP-1C design by Allen Wright to convert my ST-70 to balanced input. Question is the PP-1C design is not ultralinear and I'm wondering how to graft it to the output stage of the ST-70. Any suggestions? Is this a good choice? Hey Grey, can it be x'ed?

Just because the o/p transfer has screen (ultra-linear) taps, doesn't mean you have to use them. Just disconnect them (and insulate them really well). The Curcio ST-70 mod uses this. And sounds great.
