What do folks think?

When pushing "everything on 10" every single tube is important, pre and poweramp

I do not agree with him that you should change the PI tube every time you change power tubes. Yes it is true that the PI is overdriving but they simply do not run as hot and work as hard as your power tubes do. I have tested many PI tubes and other preamp tubes in my amps after several cycles of power tube changes and they still test strong.

He mention's some general things, but sounds more from his personal point of view more than
the Phase inverter being the most important tube in your amp.

I threw a vintage 5751 in my PI and it seemed to tighten things up a bit and bring some clarity to the tone. If that makes any sense.

Yea I like the Jan Sylvania 5751 in the PI of my 2210.

Not everytime.

"...think about a simple phase inverter change..."

"...Before you go to a pricy output set of tubes..."
