Analogue systems

I have an extra copy of the original technique book for the Ondes  
Martenot written by the inventor himself.  It has exercises and  
technical instructions that will help you perfect your French  
Connection performance skills.  Written in French-- must be able to  
read French.

The sale price from the publisher Alphonse Leduc is $51.50 US.  You  
may purchase it from me for $30 US.  The copy is in "like new"  
condition, not used.

Cheers,
Monroe
