You will need to re-bias if your go from Solid State to Tube rectifier. The plate voltage with a SS rectifier is generally higher than with a tube one. Check out the Dr Z site it discusses this topic on there. Hopefully Myles will chime in as well.

The KT-45 is the same basic setup and adjustment as the Route 66, with one small deviation. KT-45s can have a Solid State Rectifier or a Tube Rectifier; it is a matter of taste. The Tube will soften the amps response and lower its overall wattage. With the Solid State Rectifier installed, adjust the bias pot for 480 Volts DC at the Center Tap. With a 5AR4/GZ-34 Tube Rectifier, set the center tap for 440 Volts DC.
