Your amp with a 3x10 configuration is set for 2 ohms.
You could probably plug a 4 ohm cab into it safely for a little while but you
have to keep the volume down(no higher than 3 or 4 max) or you could get fly
back voltage into the output transformer which could kill it. I don't know how
sensitive those trannies are but 3 to 4 for a short period should be ok.
Your victorilux also has a 4 and 8 ohm tap inside the chasis which can be wired
in by a tech. You can also add impedance input jacks in the back which you could
attach to the output transformer, allowing you to use 2, 4, and 8 ohm
configurations.

Victorilux just to see how the 2X12 Celeston Blues sound with the Victorilux.
Will that ohm rating be safe to run with the Victorilux?
