Best power tubes for a CJ premier 11A


I just brought a minty CJ premier 11A power amp home. It came with gold lion KT-88 power tubes with about 100 hours on them. Curious as to any other recommendations on power tubes. Will the 11 handle KT120’s?
i had a SF power two many moons ago and liked the Svetlana winged C 6550’s a lot. Thoughts? Rest of the system is a SF SFL-1 signature preamp, B&W 803 S speakers, CAL CL-15 CD player and rega planar 25 TT. Wiring is musica Bella emberglow speaker and IC.
Thanks for your input!

best ask jeff at cj

not assured an amp engineered to drive kt88’s can properly bias and handle the output of the significantly more powerful kt120... the prem 11a is some 25 years old design...
