Amp biasing question


I don’t have a problem (that I know about), but from what I have read here is that:

1) if the amp is on, the preamp should be connected and powered up

2) biasing should be done with no input from the preamp.

Am I misunderstanding something?

I'm not sure the preamp should be on... unless you have a DC coupled preamp and amp, but I should leave this to the tube heads.
