Re: [ARSCLIST] Modern Cylinder Phonograph

[Robert J Hodge <rjhodge@xxxxxxx>]

Or as I once tried 45 or so years ago while trying to find a way of
doing this at home, I found that a Lafayette high frequency driver
without the horn on it would slip nicely over the throat of the rebuilt
model C reproducer. Impedance matching it through a transformer yielded
a workable signal even though it was over laden with HF noise. And most
of the frequencies contained on the record were outside the parameters
of the driver. But it did work, to a fashion. And it didn't break my non
existent hobbyist collector budget. It was completely free of hum.    

I didn't have microphones that were worth a tinker's dam.

I think the main goal, if you're doing it accoustically,  is
to have as little air mass between the diaphragm of the
reproducer  and the diaphragm of the microphone as possible.
I picked up a couple old  Shure lavs a few years ago.  


Or, as I did, locate one of those mikes that came with the cassette  
recorders a decade or so ago.  Find a piece of rubber tubing that just
fits  over the 
Edicon soundbox sleeve.  Then tape the hose (a piece about two  inches
long) 
onto the head of the mike.  Place the tubing onto the  soundbox, and the

assembly will probably not need to supported; it depends on  the weight
of the mike. 
Feed the output into a flat input of the amplifier,  preferably a mike
input. 
 The sound is quite respectable.
