Hi Andy Evans
If by adjust you mean to set the bias, it is awfully quick and easy.
On the left side of each VPA are 2 small holes with regular screws inside.
You set the amp on mute.The upper hole is to set the bias of the front tube.
The red needle on the meter must be on the very tiny area (a little rectangle) on the left of the meter. You turn the screw till it goes there.
To set the rear tube, you keep on pushing on the button which is at the bottom right of the meter during the operation.
Thats it.
Best,
