Well that is pretty odd. Not a common failure at all. The volume control in that unit is a 100 k ohm blue alps control. They can get noisy but I have not heard of the wiper in the control loosing contact with the resistive element. The preamp should be looked at and voltages checked. I assume this problem is occurring on both channels? Unfortunately, I'm on the west coast.
Audio Research LS9 volume control is not working..
My less than three years old, minimally used, Audio Research LS9 volume control is not working.
There was a power outrage in my area but I thought my Monster-Power HTS 3600 Power surge Protector would have prevent any damage. I guess not.

Pre amp volume control is not working after the power surge occured my area. When I power up, the sound volume level jumps in the middle range even with control knob in the minium level position.
I currently hooked to Rotel pre-amp without balanced mode.
Audio Rsearsch D400 solide state power amp is ok with Dynaudio Confidence2 speakers.
I tested my Audio Research LS9 pre amp to my friend's house with Rotel power amp and B&W 803 speakers.
Same thing. The volume level control knob doesn't work but the sound level jumps into the mid range.
Is this a common failure of Audio Research LS9 volume control? Anyone has a similar trouble?
Any recommand for repair services in NY/NJ metroplitan area?
