Re: 5E3/1482 Hybrid Built - Sounds Like Crap!
To me it sounds like an inaudible oscillation... Check the output with a scope. Or try to bypass various points of the circuit with a small capacitor (say 0.01uF 600V) while monitoring the current in the output tubes. If there's big change, you have an oscillation.  
 
But you said you had your grid stoppers... you removed them and the amp is louder now... So it can't be an oscillation...
