Aloe "New Lightning" 02. Nov 2008 Many Thanks to Frank for this heavy surprise package! Nothing cheap about this small Diathermy Machine! Fischer made a slight variation of this machine for A. S. Aloe - Additions are binding posts for Diathermy Terminals, and square labels for Diathermy posts. CLICK HERE TO READ THE BOOK! The Jewell hot-wire meter was made of pot metal...and turned to pot over the years... Nothing "junior" about the spark gaps on this machine - the are actually very rugged, with more surface area of copper. Inside the machine gets interesting. CLICK HERE FOR THE BLUEPRINTS! Hmm.  No. 1? Note the shoe print on the inside of the box! Inverted, the shoe was labeled "Father And Son"! Unit has a unique double condenser mounted together with a blocking condenser. Note the RF coil used to protect the meter. Sleeping beauties!
