H1 Rework Schematic

Hi, please have a look at the attached schematic with marked changes, my goal is to eliminate all un-need organ electronics but leave only what is necessary for the power amp to operate as a standalone 2 Channel power amp. Note T2 has been removed, completely from the circuit.
The center tap from T2 to T1 shows a two resistors and a capacitor 100K/.1uf/100K to ground; question, is this a hum balancing circuit, if so then it will not work without T2 correct? Is there a work around or possible may not need a hum balance circuit?
