[AMRadio] Diathermy tube for Fischer

[John Lyles]

Dave
As W7TFO correctly pointed out, Fischer was a long time diathermy 
machine manufacturer. Like others, they had their own OEM part numbers 
printed on their tubes, made by  other companies. My Aloe "Short Wave 
Unit" diathermy device has Amperex A11 triodes in it though. They have 
shorter plates than the Fischer tube you pictured, must be lower power.
