Help locating Tube Bias learning information ~ Links/Videos

[Toppscore]

Hi. I purchased a multi-meter.

Any suggestions towards good/quality known instruction
Links or Videos on beginning "how to BIAS guitar amplifier tubes"?

Mostly, I own vintage Fender tube amps.

Please help me locate some "known" quality
beginning TUBE BIAS instruction materials.

Thank you. Toppscore

Thanks, Xtian and Martin.
"What is Biasing" and "The Last Word On Biasing".
I've my homework cut out


Anyone have links or articles or videos with regard to
vintage 1950s & 1960s Fender amps?
And the settings for each amp?


I checked Ampwares and the Fender Field guide. The information
seems incomplete. Basically listing each amp with a
* Cathode Biased
* Fixed Bias
* Fixed Bias with bias adjustment pot (or) Fixed Bias with Bias Pot
* Fixed Bias with adjustment pot or balance pot (AA769, AA270)
* Fixed Bias, nonadjustable

There may be others . . . . . but did not find the correct Bias settings.
