what to do............

here is what i have..........
a conrad johnson 2300a, just back from having both channels redone and rebiased and other stuff done to it.
a pv10al, with little use and currently tube rolling, with new rca 12au7s clear tops. (my tong-sols have not arrived yet)
alon IVs just had the woofers reconed, midrange and tweeters replaced and voice coils and xover reworked.
a rotel lcd 975, my dream system.

my problem is i get no gain, when i turn it up. i use to be able to listen at 9 and 10 oclock, now i have to turn it up to 11 to 1 oclock to get the same response. what am i doing wrong, have i missed something some where. the sound is great, crystal clear. the problems is when i turn it up, that i cant figure out whats wrong. i have heard that certain tubes will make you lose gain, but i have tried putting the other tubes back in but with the same results. i have noticed that at night this problem is lessened,that makes me think of a conditioner. but i have heard the pro's and con's of that debate.
