The 41 tubes do not employ a phase splitter stage, but have an odd circuit where one G2 is to B+ and the other G2 via a 3.9K resistor with feedback capacitor to the other tubes' G1.
The cost cutting went too far there. That arrangement won't sound that good. I'd install a real phase inverter tube somewhere, probably under the chassis.
