[78-L] EQ ideas for transferring acoustic 78s?

[Malcolm Rockwell]

Yeahbut... wouldn't that be a 50Hz hum in Canadia? Or, if the record was 
made in the US and actually carries a 60Hz hum along with the 
information plus a 50Hz line hum in your power train, you'd have the 
worst of both worlds?
Also, I understand that what we call 60Hz hum is actually 120Hz hum - 
what we're hearing is  actually the 2nd harmonic, not the fundament. 
Means you'd have to rolloff around 250Hz to catch the 1st, 2nd & 3rd 
harmonics.
No?
