I would *never* trust my ears alone to do restorations. I use a  
spectrum analysis (a function of the sound editing software I use) to  
determine the proper equalization, not what it "sounds like."  
Although I can hear a television's horizontal oscillator (15.734.26  
Hz here in the US), it's doubtful that most 78s actually have such a  
high recorded frequency at any appreciable level. Late ones, maybe,  
but nothing prewar.

That said, I do have the treble control on my amp nudged just  
slightly north of center, as a matter of preference. Same with the  
bass control.

Take care,


Joe
