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

Just a note you can use a regular patch cord from your transport to your DAC, it just won`t have the Bandwith as the Digitl cable.It probably would still sound better than the glass you were using.My first reply to your problem I said [Mode switch] I ment [In put switch].Are you sure you were ported in the Direct in? Had the toggle switch in the dirrect position?
I have An LS3, when I first turn on the unit the Mute light is dim lit for about 3 sec then goes bright.Does your unit do that? It sure sounds like your not patched in correctly.It sounds like cross talk within the unit,you know,if your not using the [direct input jacks] and say for instance your were patched into the CD input but had your mode selector switch on AUX, ect.The volume control will acts like you have discribed.
