Operating frequency and Ua
When the operating frequency above 30MC, Ua and anode input power should be reduced as follows:
Operating frequency(MC) Ua and anode input power
60 89%
80 70%
100 55%
 
When it is in constant working, the anode should not be allowed to have slight red; when in interrupted working, it should only be allowed to have perceptible slight red.
