BIAS TUBES VM220 ARC


I have the VM220 mono blocks by ARC. My problem is that on two pot #v1 and #v2 my millavolt meter reads -17.0 can not get anywhere near 65db's. Can someone please guide me in the right direction.

Sounds like a bad or poorly matched tube-set. Try switching the offending pair to the other amp and retry. When all is working well, this should be an easy adjustment.
