[NJARC] WWI headphone impedance

[Alex Magoun]

    Joel Cohen is working with me on  a number of exhibit projects for the David Sarnoff
Library, one of which involves attaching a block oscillator to our telegraph key and a
pair of WE 509W headphones.  He's not on the internet, so I'm asking what's the
impedance of the headphones and will the block oscillator drive them?
    thanks,
Alex Magoun
