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.
