The manual says about 100mA. Measuring 50mv across R24 and R25 in parallel corresponds to 100mA. Adjust with R9.

Thanks Gold!!!!
Done...think will be the same for the monitor amplifier...
I'm starting to become friend with my Vg66....

On the Feedback amplifier R4 should be adjusted for least THD and symmetrical clipping. The monitor amplifiers are identical to the drive amplifiers.
