Pre-Amp Problem Opinions Please

HI TO ALL.
I own an audio research LS3-B line stage that bought brand new in 1996 i believe it was. it has very few hours on it,and it was sitting on my rack for all this time,really!
I was using my conrad johnson intergrated . I just bought some used digital gear from audiogon and decided to re-arrange my system and hook the LS3-B in. after all hook ups and everything I sat down for some listening and to my disbelief I noticed that volume control is acting up big time.
At 7:00pm position is off(which is normal) at 9:00pm position you get barely sound ,at 11:00pm is the loudest it will get(but still very low volume level) and at 12:00pm sound goes down again and at 1:00am there is no sound(normally it should get louder there).
Also I notice pops every time I touch the volume control,and sometimes pops heard even if I am not touching or turning volume control at all.
My rest of system if it matters is,,Krell md-1 transport
audio research dac-3,conrad johnson mv-55 power amp,and mission 753 3way speakers.
Any help is greatly apreciated.
best regards
George

If you havn't used it at all or excersized the controls, it may just need cleaning.

Are you sure it's hooked up properly? Also check to see if you have a tape/rec button on the pre. When this is depressed you will only get normal volume when you are recording a tape.

Can you tell us what component connect to what? It sounds like ground loop issue too. Volume control rarely goes bad like that. When you have ground loop issue, you can hear clear loud pop when your hand is touching or near the volume control knob (due to static discharge into the ground loop.)
