KT120 for Primaluna or Mystere?

Would anyone know why Primaluna and Mystere do not recommend KT120 tubes as Kt88 replacements? Is it because of their auto bias feature?

I noted the input/driver tubes are different and that the transformers may be different as well, but not too sure on that one. The lesser offering drives EL34s the bigger amp can use a variety of power tubes which you see in Prima Luna as well.

The sound from this tube however was not to my liking . It did the extremes quite well but the mids were MIA . Hope this helps .
