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

[David Lennick]

Actually I've had discs with 25 hz hum, recorded in Canada in the days when 
Toronto ran on 25 cycle power (remember "cycles"?). Never 50 though. What's fun 
is a dubbed lacquer, possibly off speed, where you don't know which hum to 
pitch to.
