CV2009 grounded-grid triode
 |
This valve measures 55x21mm
overall and has 8 tags including one connected to the central spigot. |
This valve is a modified CV417. Note that the valve has the original CV417 markings painted out but retains the 6AQ4 markings - which is no longer valid (except electrically) due to the modifications to the base.
