anyone use KT120's or KT110's tubes in MAC 275 ?

I've read nothing but good things on the KT120 output tubes. Has anyone used them vs. the KT88's. I'm am wondering if the KT120's will work well in the MacIntosh 275 Amp and provide a good upgrade or perhaps the KT110's?
Thanks

In the KT88 compatibility test performed by Fluxion audio technology, it was concluded that If an amplifier is designed for KT88 in the case of mc275; KT120 is interchangeable without any circuit modification and bias adjustment.
