1) Circuit losses are not included.
2) Even during modulation the indicated maximum ratings must not be exceeded. It has to be observed that the plate dissipation
will increase to about 1,5 times the power dissipation stated for the carrier value during 100 % modulation.
3) Modulation of screen grid via separate transformer winding.
4) Maximum values at
U
A
= 0 V.
5) Average values at
m
= 100 %.
