Hi Guys
Despite the fact TUT has been out since 1995, people still ask about the 300V rating for 12AX7 and similar preamp tubes.
12AX7 has a flash-over rating in excess of 540V.
The reason for the 300V rating is to accommodate the flyback voltage with an inductive load, such as a transformer feeding the next stage.
Have fun
