Extras ▼

 

The CV509 is the 6V6G audio beam tetrode. This Type was very popular as the final audio stage of radio receivers.
The valves were capable of push pull use but the normal environment was as a single end output stage.
The reverse of the envelope is plain. Through the dark glass the outline of the anode can be seen as can the control grid cooling fins at the top.
The classic envelope has a maximum diameter of 44 mm and a length excluding the IO base pins of 101 mm.
