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.
I am not familiar with your amp, but what are your trying to measure? Most tube bias are in the mili-volt range. Are you trying to adjust the bias pot to read 65 mv? It sound like you multi-meter is on the wrong setting.
