that is odd, did you replace C16? and if so did you make certain it was the same value? changing the value there can change the voltage.
if you haven't replaced it yet, replace it.
although I wonder if having two bias circuits coming off C16 has changed the behavior of the circuit. if you've already replaced the cap, maybe try increasing its value a bit. I"ve heard of people switching to a .1uf to adjust the bias range for KT-88s. apparently it works.
