Question PSRR

Hi all!
Does anyone can define what it means to a great PSRR figure in tube preamps or cathode followers?
What does the abbreviation PSRR?
Thanks for the help!

PSRR
Power supply rejection ratio. There's a superb explanation and relevant formulae in "Valve Amplifiers" 4th edition. If you're going to play with tubes, you really ought to have the standard reference at hand- it will save you a lot of time and effort.

PSRR....

The ability (Or not) of a circuit to be immune (Or not) to any noise and hum derived in the Power-Supply stages and present on the supply lines to the circuit....
