The HV supply uses a tube V427, to regulate the +300V supply. The manual lists V427 as a [[7734]], a triode-pentode, however some models contain a small circular adapter board (670-1860-00,388-2423-00) to adapt the [[B9A_base|noval tube socket]] to a [[Compactron_base|Compactron socket]] and use a 6G11 double pentode instead. The adapter PCB connects the screen grid and plate of the beam power tube together in a triode configuration. These models also have 6G11 printed below V427 on the chassis. | The HV supply uses a tube V427, to regulate the +300V supply.
