Schiit Freya plus. Is this an upgrade?

Can these globe fubes fit in a Freya? The spacing is tight.

I wish people wd stop slating JJ tubes based on forum stuff from 10 yrs ago. I use JJ KT88 in a SET and 5751 in a pre w no problems.
The SET has been totally abused by the wife, switching off then on, unplugging stuff causing terrible noises etc. Tubes still work fine
