摘要：
In a high-frequency generator 1 having a multigrid electron tube 2, a current source circuit 10 connected to the control circuit 3 or the screen grid 4 of the electron tube 2 is arranged as an optionally adjustable current source which is also coupled to the main current path of the electron tube 2.
This defines the grid dissipation and also extends the useful life of the electron tube 2. The electron tube 2, if the current source circuit 10 is connected to the screen grid 4, is further safeguarded in a simple manner against an inadmissibly high screen grid current accompanying an occasional anode voltage drop.
