Wsah4700, wsah8060, wsah8084

Hi all,

I noticed in the building manual from the WSAH4700, which stating that the power resisters 23,24,25,26 has to be placed if there is a simple power supply in the WSAH8086, I noticed on schematics, there is a symmetric circuit on the amp. +40v -40v but I miss So just to be sure, are these resistors needed?
Best regards.
