How much time do you have on the Mullards? They need at least 40-50 hours to burn in.

I use Mullards almost exclusively and have never found what you state to be the norm. Maybe new, right out of the box, but never after they've burned in.

Give them some time to break in...

they were used.............
A point of information: "NOS" = "NEW Old Stock" = unused.

As usual Al is correct, although many sellers claim that they are selling NOS tubes which are actually used.
