The Turn Of The Century Electrotherapy Museum http://www.electrotherapymuseum.com H. G. Fischer Model 200 Diathermy From the family of H. G. Fischer.  Many thanks to Jonathan, Hannah, and Warren Fischer. Massive 120 pound Diathermy Machine - Model 200! Back-conforming electrodes connected with massive conducting cords! 10A!   A seriously heavy duty short wave machine! The meter has the classic Fischer logo. This style of writing is found on many Fischer blueprints. The handsome company logo is as large as the meter!  The massive unit contains a radio tube nearly a foot tall! (C) Jeff Behary - 19.
