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

The volume control is just dirty.
If your are not handy with stuff, ask a techi friend to clean the volume control. Radio Shack would have a spray cleaner if yours is suitable for that sort of cleaner.
A long time to sit and get grunge on it.
A faster way to partially clean it is to turn it off, then rotate the control gently from minimum to maximum like two hundred times. That should get rid of the pops, and some of the grung, but it really does need to be cleaned inside.

Also if you NEVER turned it on in all those years, some of your caps may be damaged... Try cleaning the volume control first though.
Even if stuff is not connected and just sitting, it should be powered up at least once a year? to keep the caps in shape.

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