Mark VII power tube colours

[Voyager72]

Hello fellow Mark VII users

curios which bias colour for the STR445 came with your Mark VII?

The first Mark VII came with green. Those got swamped out at gig level and lost all detail. Sounded more blah but at lower volume settings the amp was ok, even with the different power modes. I ordered some STR445 not thinking about requesting any color codes and ended up with two complete quads of yellows. Those work very well at any volume.

Second Mark VII was shipped with yellow coded STR445.

Thanks @bandit2013
Interesting the green and yellow being one gradation apart behave different.
