Yeah I took it awhile ago just to have it double checked.And the tubes were matched up,but when checking the Mv/Ma one was hotter than the other.So now they are trimmed up and even at about 60% I believe.

My pre bias with new tubes were at 39 one tube and the other about 40! we set it at 38.5 still a little hot but I was use to the higher settings
