| Well... yes they can... and yes, it seems to be tech time.....
That said, why are you replacing tubes?
What's the background to this question? Seems that there HAS to be something more going on.
If something drastic happened, then the advice is good on the basis of possible damage.
If you are "just replacing tubes", and the old set did "work" even if they were weak, then, there is some question about the amp itself...... and maybe the tubes. Assuming that the tubes really do work in one side but not the other.
Do the old tubes still do the same thing? Is that why you replaced them?
if only the new ones do it, there is a chance the tubes are too "hot" for the bias range in the amp, possibly not by much, so one side is for some reason capable of just reaching the needed level. They might be real "limit case" tubes that need a lot of bias.
if that is not the case, and the old tubes did it too, probably either the bias lights are bad, or there is another problem. Also tech time, but expectations of what might be wrong are different in that case.

There are no GOOD techs around here (one suggested my tubes were not matched appropriately and needed to buy HIS tubes... the more he talked the more i could tell he needs business and not interested in FIXING what could REALLY be wrong... so i gotta look to Los Angeles for a decent tech... and recommendations?)
