The Link is a excellent collection of information.
The DIY Audio Build thread covers very important points, especially for the Valve Selection.
Reading through some of this info brought back the kind of thinking I was experiencing when having a Custom Built Valve Phonostage produced for me.
Burn In periods and select component changes can move a build into a place that seems beyond achievable.
A second Phonostage I own was modded to work with E88CC Valves,
the Tube Rolling experiences were very revelatory, and I have recollected the good memories of the Mullard when put up for audition.
Good Luck if this is your chosen route and do share your experiences.
