Of course th unit still works fine.

After replacing the tubes AND calibrating I doubt that you can hear a sound 
difference. You only can measuere it.
If you do not calibtate it, of course you hear it, since the gain changes 
significant.

NO slight gain adjustment but an immense gain adjustment.

> Does digitech still sell tubes for these?

No.
