One section is a small triode that amplifies the 0 to –24V input swing into a 0 to +250V swing that, in turn, drives the output deflection node. The plate of the triode has a 470k load to +250V and drives the deflection node on the other section to deflect the output beam on the fluorescent target painted on the side of the glass envelope.
